List of AB (connected) bottle base mold codes

List of mold codes recorded on the bottoms of “AB-connected” (AB ligature) antique          glass beer bottles (c. 1905 – 1917)

  Usually alpha-numeric (letter followed by a number), these are believed to be “shop marks” or mold identification codes, embossed on the bottoms of antique mouth-blown (handmade) crown-lip “export beer” bottles. The “AB-connected” mark is positioned directly above the code.  (To my knowledge, no one has yet proven exactly what these codes mean).    Some of the letters are followed by numbers ranging above 40, yet other letters tend to be accompanied mostly by numbers on the low end of the spectrum. Some letter/number combinations seem more common, others scarce or simply not yet reported.  Perhaps time and more research will reveal the “whats” and “whys” of the code numbers found on these containers.

The AB-marked bottles are generally believed to date from the c. 1905-1917 period, and were made by Adolphus Busch Glass Manufacturing Company and/or American Bottle Company (see page here with more information).

They are typically found in light blue-aqua glass, occasionally in light green or sun-colored amethyst, and were evidently produced in VERY large numbers, with many iron or steel molds for this particular type of bottle being utilized simultaneously. The bottles were  made in two sizes, the so-called “pint” and “quart”, in reality holding (respectively) about 12 ounces and 24 ounces.

These codes are confirmed / reported on actual bottles. If you have codes that don’t appear on this list, you’re invited to email me (contact info at lower right corner of any page on this site) and I will add them to the list with credit to contributor.  This is a list in-progress, first published on the web 2/24/2014.


 1) All listings followed by the notation “TUR” denote bottles recorded in an unpublished manuscript detailing an archaeological excavation in Tucson, 1967-1973: “Beer Bottles from the Tucson Urban Renewal Project, Tucson, AZ”, by James E. Ayres, William Liesenbien, Lee Fratt, and Linda Eure — 1980, Arizona State Museum.  Some of the AB bottles recorded from the TUR project bore embossed heel codes (7-B, etc) which may be date/plant codes (such as 1907-Belleville,IL plant??). Those heel codes, if present, are noted here also.

2) Large numbers of these bottles were used in the construction of the Rhyolite Bottle House (Tom Kelly’s Bottle House), Rhyolite, Nevada during the 1905-1906 period. Just a very few of the codes are recorded below which I’ve been able to discern from studying several closeup photographs of the outside walls. It is certain that many other codes can be found on the AB bottles that were used for it’s construction.

3) Base codes submitted by archaeologist Carol Serr (CS) were recorded on bottles and base shards from several archaeological projects in the San Diego, CA area. Thanks alot, Carol!

4) Codes followed by the notation (Chena) indicate bottles (whole, or base shards) recorded during the Barnette Street/Chena River Waterfront archaeological project at Fairbanks, Alaska in 1992/1993. Many artifacts were found dating from the early 20th century, including many AB marked bottles. Historical Development of the Chena River Waterfront, Fairbanks, Alaska: An Archaeological Perspective (CD-rom – 1998),  edited and compiled by Peter M. Bowers & Brian L. Gannon, with Catherine M. Williams, Andrew S. Higgs, Amy F. Steffian, Owen K. Mason, Ronald D. Navarro, Debra Barringer, Stacie J. McIntosh and other project participants.

5) None of the listings from auctions mentioned below imply in any way that I endorse, promote, or agree with the description or value listed on any of those bottles.  The information was gleaned from ebay auctions merely as a tool to assist in compiling known and reported letter/number codes on these bottles.

6) Please note that some bottles are also found with the “AB Connected” mark along with “CO” and they are also seen with the same type of letter/number combo on the bottom. I have begun including them in the list (8/23/2015), but always with a notation that the “CO” is included.

  11. Anthony Sylvester says:

    Hi David,
    I dug an AB connected with base mark H1 in an amethyst color out her in Hawaii. I tried emailing you but it does not seem to work or I donʻt understand the directions. I would like to list it here.
    Mahalo, Anthony

    • David says:

      Hi Anthony,
      Thanks for the info. I will update the list shortly. My email address is written that way (at the bottom right of any page on this site) to help reduce spambot email address harvesting.
      Take care,

  12. Ray c says:

    Hi David, just found a AB H 10 aqua blue Quart bottle and a aqua blue pint bottle in Cashton Wisconsin. The pint only has 7 5 13 or it might be 17 5 13 on the heel. Just found your web site this weekend. Great job,Great info. All the other emails i sent you, the bottles all came from the same pit in Cashton. Thanks keep up the great work

  13. Ginger says:

    Hi all! We just found a AB M 5 picked up on a construction site in Telluride Colorado.

  14. Rich Ballweg says:

    Today I found at a church rummage sale an AB T12 and paid $1.00 for it. Any idea of its age? Did not see it on your list

    • David says:

      Rich, I cannot pinpoint the exact age of any of the AB-connected bottles, as explained in the article (see the other [main] article about these beer bottles; there is a link embedded in the text near the top of this page).
      Best regards,

  15. Rich Littlefield says:

    Found a quart size base shard in Hazen, Nevada. The number below is “16”, no letters. This area was pretty well worked over by diggers many years ago and someone left a piece of history behind. Also noting that the AB logo is wider with thinner lines than on other same-size bottles. Don’t know if it is taller than other logos as the top 10% of logo is missing. Having a base shard made it easy to overlay on other AB bottles that I had. (picture available)

    Dug up an ab y 23 bottle in my front yard gardening…Duane Syverson…Guthrie Okla

  17. Alex says:

    During the analysis of historic artifacts from our 2016 excavation in Tempe, Arizona, I identified an aqua bottle base with the “AB-Connected/ X 2”

  18. Jeremy and Bethany Crenshaw says:

    We dug a AB marked K 12 near Palmer Alaska

  19. Daniel Camacho says:

    David, I just now cleaned the C1 bottle that I dug and is listed on your list. I just noticed that it’s marked 9-B. I don’t know if you have been wanting that info also. Now I’ll need to go and check the rest of them. Take Care.

  20. Jeff shurtleff says:

    Found April 5 2017 at Glenwood springs elementary school construction site AB, v1

  21. Mike Schend says:

    Have a AB x3 which I didn’t see on your list. It was found near Fresno Montana by Frank Schend.

  22. Stephen Parker says:

    Ab bottle A10 value

    • David says:

      Stephen, the typical blue-aqua colored AB/connected beer bottles with codes on the base are very common and have only nominal monetary value to antique bottle collectors- perhaps 1 to 4 dollars or so. Such bottles often appear on ebay and do not sell at all unless the minimum bid is set very low. However, those in unusual shades of color, such as amethyst, may sell for more.
      Best regards,

  23. Kristie & Shane Davis says:

    Me and husband have an AB K23 aqua colored glass with uneven bottom inside and looks to be swirls on the top. Didnt see it on the list. Thought you might like to add it. Thanks.

  24. John Hodgins says:

    Hi David. Wonderful website. I have an AB connected light aqua blue bottle with the code E 2 to add to your list. It was found on southern Vancouver Island British Columbia Canada.

  25. Carolyn White says:

    Found s17 several years ago in south Georgia. Is it worth anything?

    • David says:

      Carolyn, the AB-connected beer bottles are extremely common, (made in the millions) and even though they are at least a century old, because of being so plentiful, and because there is no embossing (lettering such as brewery, brand name, city or state) on the front, but only the glass maker mark on the bottom, they don’t have very much strict monetary value to antique bottle collectors. On average, they might be valued at 1 to 4 dollars (note: this is just my own opinion), although they may be priced much higher at antique malls, flea markets and on online auction sites.
      Although I’m sure some of the code number/letter combos are much scarcer than others, there is not currently a lot of interest/demand in these bottles, and so it’s difficult to know which ones are harder to find. And since there is little collector demand for these bottles, the scarcity of some variants has little or no impact on “market value”.
      Best regards,

  26. Brian Dierks says:

    I dug up a bottle with the AB mark and the number T 31 while excavating near a building in Trinidad Colorado… I didn’t see this on your list… Wondering if you could tell me more about it

    • David says:

      Brian, all of the info I have concerning these bottles is already posted on my two webpages concerning them. I will add your find to the list. Thanks and best regards,

  27. Lee Williams says:

    U13 on the bottom of an AB blue bottle. Found in Montana.

  28. Steve Hale says:

    Hey David – Went thru my Pile and found a standard aqua beer with an R 1 code (which I notice is on the list), but the AB connected is fairly crude. Looks to be an early Crown Top to me – lots of bubbles, etc…? Steve

  29. Kyle Richter says:

    Found one this weekend completely intact. We live in Mascoutah Illinois which borders Belleville Illinois and is just outside of St. Louis. The bottle contains the number S-17 and is light blue in color.

  30. Reb Willows says:

    My father found a small cache of Coors bottles in the Colorado mountains near St Elmo’s found in a barrel near a mine in the late 1960’s. I have 2. One is the A.B Co V 8. The other is a V 11. One was given to the corporate Coors since it still had a Coors label. My folks left quite a few in the barrel. My mom has a bottle with a label still and some of those bottles in the attic.

  31. Peter says:

    Found a bottle AB A8 Belen rail yard, Belen New Mexico bottle is in perfect condition four feet underground. Interested in finding out what year this would be thanks.


    • David says:

      Hi Peter, all of the information I’ve gleaned about these bottles is already presented in my two articles concerning them. Basically, these bottles were evidently made between 1905 and 1917. For what it’s worth, it appears that no particular “AB-connected” beer bottle can be dated to an exact year.

  32. Daniel Camacho says:

    I just dug the base to an AB connected B4 base mold.

  33. Bob Brown says:


    A collector I know recently found an Amber 7up ACL 7 ounce bottle with the typical swimsuit girl ACL label that has a heel mark of 29S6. That code is the only embossed marks on the bottle and there is no AB accompanying it. According to Bill Lockhart, the 29S6 mark was used by the American Bottle Company in 1929 and also by the Owens-Illinois Glass Company in 1929 when Owens-Illinois bought American Bottle that same year. However, because the bottle has a 7up ACL label, I can’t help but wonder what the connection might be between an apparent 1929 bottle and what should be a circa 1935-36 7up ACL label? Is it possible that its a 1929 ACL or is it more likely a repurposed bottle that Owens-Illinois used after they bought American Bottle?



    • David says:

      I can’t say for sure, but I would guess the bottle was blown from an older, re-used bottle mold on which the heel mark (engraving) had not been ‘erased’ (filled in so it would no longer be visible). Many times molds were re-tooled and used again, since molds were and are expensive to produce.

  34. Nicole Doiglas says:

    I pulled one out of the mud of the San Marcos river in Texas today with a code that reads t-30

  35. Hi there,
    I found two bottles this week-end, one of which you already have, P 23, and another one you don’t, M 13! This was at an antique/flea market in Québec, Canada.


  36. Jeff mcKenzie says:

    I have one dug up in Hebron Nebraska, mint, has wire and stopper, AB 4 mark

  37. Trevor Hayes says:

    My brother found two Regal Lager bottles in Niagara Falls, Ontario while doing a Ren-o. One of the bottles has AB S-16 on the bottom and the other is blank. Regal Lager was a beer company located in Hamilton, Ontario, Canada. around 1915

    • David says:

      Hi Trevor,
      Thank you for your post and the information. This offers evidence that some of the “AB-connected” beer bottles could have been made as late as 1915. It is also very possible that the bottles in question had been re-used and had labels pasted on them several years after being manufactured. It was very common for all types of bottles to be saved and reused by both businesses and individual consumers, especially in the 1800s into the very early 1900s. So-called “bottle shops” operated in some large cities and they served as recycling centers and second-hand sellers of glass.

  38. Brandon Holthaus says:

    I found an AB connected beer bottle underneath a house in Virden, Illinois today. It has the Y 22 on the bottom, but not the small co to the right of the AB, as spoken about above on the list. Curious to know any other information. Thank you.

    • David says:

      Hi Brandon,
      Thanks for the note. Sorry, but I don’t have any other info other than what is already written on these pages. I’ll add your find to the list.
      Take care,

  39. Erika Gorman says:

    Hi! We found one in mint condition this weekend….it survived the Las Conchas Fire by the Valle Caldera in Northern New Mexico and was unearthed by runoff erosion post fire. We were walking through the runoff debris this past weekend and found it sitting there full of dirt but otherwise unharmed. Tough bottle to have survived so much. It has a J13 under the AB. Thanks for putting this page together!

  40. Cheryl says:

    I was hiking in the bush today on Vancouver Island B.C Canada today and stepped into a mud bog and noticed the bottom of a bottle . Dug it out and to my surprise it was a AB p24 in mint condition . It’s a real head scratcher as to how it was there .

    • David says:

      Hi Cheryl,
      Thank you for your post. Probably someone was drinking beer while out hunting or hiking (many years ago) and disposed of the bottle in the most convenient way they could think of………merely tossing it aside.
      Best regards,

    My 4 yr old son loves old bottles especially blue ones. Found an AB A 1 aqua in color at a thrift store for $1.99 as part of his Christmas gift. We had no idea of its age or origin, how exciting! Thanks for the information. We live in Comox Valley, BC, Canada.

  45. Samantha Johnson says:

    Hi, just wanted to say your page was very helpful! I recently found a bottle marked connected AB E9 in IOWA I didn’t see it on your list!!!!

  46. David says:

    Hello David-
    Great site with lots of useful info!
    I found an AB connected bottle with C8 on the bottom at a thrift store in Marshall, Mo today. Beautiful bottle with lots of really neat mold marks, bubbles in the glass, lines, etc. and NO chips, cracks, dents or dings. I gave $1.00 for it, hope it wasn’t overpriced!

  47. Andrew says:

    Greetings. Found an aqua blue bottle in 2012 marked AB B 34 on Atkinson Island, Galveston Bay, Texas.

  48. Will Grice says:

    I found an slightly reddish, amber bottle, with faint 2 casting lines from top to bottom. On the bottom, is a connected AB (like pictured above) with a distinctive 71 below it.

    So cool!!!…We just found one in Guam. The code is AB L6. We found it in the water, at low tide, at Gab Gab beach which is on Naval Base Guam.

  53. Mark Giovagnoli says:

    We have a brook in our back yard in Enfield, New Hampshire with a lot of old broken glass dating back to the late 1800s and early 1900s. We did find many intact bottles and one of them have the AB symbol with H8 on the bottom. Can you tell me anything about it I am interested in learning about it.

    • David says:

      Mark, all that I know about those AB bottles is what I have already written on this webpage and the other page about the AB bottles on this site. Did you read both pages?

  54. Noelle Mitchell says:

    Hi David,

    We are landscaping in our backyard and the crew dug up an AB bottle with an M6 below the connected AB mark. We are excited to know that the bottle is about 100 years old. We dug ours up in a neighbourhood in Victoria BC Canada where many of the homes date to the early 1900s. We really appreciate your website! Thanks for the information. Noelle

  55. Jess Cost says:

    I’ve found an AB S-3 with an “S” embossed under the AB while going through my late mother’s things. She was an avid bottle digger back in the day. Aside from being dirty on the inside, it’s in great shape.

  56. Jeff and Elizabeth Yates says:

    I have a AB connected and B 33 on the base. I found it when my husband and I were tearing down an old mobile in Rainier, WA.

    My comment is awaiting moderation? From January 2015

    • David says:

      Hi Brett, I added your AB bottle to the mold codes list back in January, and wrote you a private email, thanking you for the reported find. Do you check your email spam/trash/junk folders? In any case, please be aware I do not approve/post every single comment I get to this site, or the site would soon be OVERWHELMED with thousands of posts for the web-surfer to wade through, and would cause the webpages to load somewhat slower for those with older or slower computers. I only answer about 30 percent or less publicly, but many are answered privately. I can barely keep up with answering comments/queries on this site, as, believe it or not, I actually have a full time job in my “other life”. I do not sit in front of my computer all day. Many questions are sent to me which I am simply unable to answer, and alot of them are questions that are ALREADY answered somewhere on my site, or can easily be answered by taking a bit of time to do some keyword searches online. I hope you will understand. Sorry if this causes any inconvenience to you.
      Best regards, and Take care, David

  60. Delfina Lampi says:

    Hi David, I was going thru my vintage bottle collection and found a light blue ” AB ” connected beer bottle with ” R1 ” embossed on the base. Your site was helpful in finding out a little information about it, thank you. I wish I could tell you more about exactly where it was found but I purchased it over 10 years ago in an antique shop in the Southern California area likely between Fresno California and Riverside California. Hope you can add this one to your list !

  61. John says:

    Today I found an AB connected beer bottle with P13 embossed on the base. Found sticking out of the ground not far from the Budweiser plant in Fairfield, CA. Washed up beautifully, very clear non-scuffed bottle.

  62. Bonnie Kay says:

    I received the same bottle a few weeks ago with the same AB and s 8. It was dug up weeks ago at an excavation site here in Winslow, Arizona. A historic building, downtown caught fire approx. a year an a half ago & masses of bottles are still being found. I was lucky enough to be given a few. Also, this page was very helpful and easy to find when I searched the bottles’ markings. Thanks. -Bonnie Kay

    • David says:

      Hi Bonnie, Thanks for the information, and your kinds words about the site! I have added your bottle to the list of mold codes reported to me. Best regards, David

  63. Leann P says:

    I found an aqua AB bottle with the “B 7” stamped on the bottom. The B was actually stamped twice! Found in Carbonado, WA, in our horse pasture.

    • David says:

      Hello Leann,
      Thanks for your post! Your bottle has what is called “ghost embossing” when a part of the mark appears in duplicate–usually the secondary embossing is fainter. This is caused by the molten glass being blown into the mold and the glass shifts very slightly, “picking up” a part of the engraving (this may happen in just a second or fractions of a second, and might be somewhat akin to the idea of blowing a “balloon” of bubble gum, sucking it in slightly, then blowing it out again) before settling into it’s final place against the inside of the metal mold. I will add your mold code to the list. Thanks, David

    Just dug a blue bottle AB connected, P24 on the bottom. Southern middle Tennessee. Bottle in great shape except for some white staining on what looks like the outside and inside.

  67. mark reid says:

    found this at an auction in southern Indiana. it is ab connected with a p 8 on base and a 8 b on heel.

  68. Daniel & Serena Camacho says:

    David I hope you get excited like I am over what I’m about to tell you. I was out digging with my bud again Saturday and I see that I have three more AB bottles not listed in your data base here. And my wife thought it was cool that you added our names giving us credit and what does it mean. I told her well honey it means you have the only documented bottle of that mark, only one in existence until proven otherwise hahaha.
    Off the Six AB connected marked bottles three are not on your list (E-11, V-11,& V-15) I did manage to dig two more v-18 and one H-13 also. I’m going to have my buddy go through his bottles also for you. Thanks for putting up such a wonderfully and informative page. Daniel Camacho

  69. Daniel & Serena Camacho says:

    David,I’ve been digging bottles lately near Fairbanks,Alaska where some gold miners worked around 1908 at the earliest that have the AB connected base mark and of course trying to accurately date them I stumbled on this page of yours. So I went through my cataloged notes and found these AB connected base marks in my collection not listed here on your page. I hope this helps.
    H15,H26,H13 and Y3. Also my wife Serena dug one yesterday that is H17.The H17 is such a super weak mark you can barely make it out. I’m assuming the mold was pretty well used and worn by the time this bottle was blow. Daniel & Serena Camacho North Pole, Alaska.

    I found a bottle in a old homestead in the mountains in 2013, that has the AB (connected) A15 on the bottom, really cool! Thanks for sharing info on the bottles! Was really interesting and informative!

  71. Debbie says:

    Hi David, I just found an ab connected Blue bottle complete. The markings on the bottom of this bottle is AB.Co under that is The letters BIG and under that is 05. I’m stumped, thanks for any help. Debbie

    • David says:

      Hi Debbie,
      [Readers: Debbie send me a pic of the base]. The second line of text is supposed to be “B 19” although it does indeed look like “BIG”. I have not attempted to compile and list the base code numbers seen on the “AB[connected] CO” bottles, only the ones with just the “AB”[connected] . The “AB [connected] CO” bottles are not as commonly found as the “AB[connected]” ones. Most of those bottles seem to follow a similar pattern of letter/number combos on the bottom.

      In any case, it would seem that the ‘AB CO’ stands for American Bottle Company. Your bottle was likely made sometime in the 1905-1917 period. It is possible the “05” stands for 1905 but that is not certain by any means!! Usually, when a number appears on the bottle that is believed to be a date code, it is on the heel, not the base. Since this is on the base (third line of text) this presents more questions than answers!

      Take care, David

  72. John Napoli says:

    The other day I dug up an AB connected beer bottle with M 12 embossed on the base. This was dug in an area that seems to range from 1910+/- to around 1930.
