It's also listed by Brunk but with no attribution. Yours is a new example C-B-D. They're presently known pieces on other Large Cents... 1794, 1816, 1817 and one without a date. This looks to be a possible silversmith stamp. I'll check it out and get back to you. Bruce
I couldn't find any listed silversmiths named Auburn, but I think the stamp might be a reference to a city name such as Auburn, NY. In my search I came across an early clockmaker and silversmith from Auburn named Asa Munger. He did business as Munger & Benedict (Theodius Benedict) from 1818 to 1820 with a different partner from 1825 to 1833. Since he practiced during those early years all the known specimens would fit nicely into that period. Even more interesting was the fact that in addition to his name stamp he sometimes used an Auburn stamp very much like yours. I saw an image of one, but it was so small and indistinct that I couldn't match it to yours. This is a possibility but not a sure bet, C-B-D. A nice counterstamp nevertheless. BTW, can you make out the engraving the stamp is struck ove?. It could possibly give a clue to identity of the issuer. Bruce
I saw where there was one stamp that was "AUBURN" And another that had a period at the end, so, "AUBURN." Two different stamps?

I'm just seeing the one stamp, C-B-D. The "Auburn" with a period. I was interested in the engraved (?) letters or initials also present on the coin. The one letter is a fancy "V" but I can't make out anything else clearly. Can you decipher them? Bruce
Very interesting about Asa Munger. I’ve owned several of his clocks and they’re very different than similar Connecticut shelf clocks. Very well made and he was a bit of a mechanical genius. Would be very interesting if the stamps on the coins were his
Another possibility is the tool manufacturing industry in the 19th c at auburn Prison. There were a lot of tools especially wooden bodied planes that were made there by various contractors using prison labor. T J McMaster was the major one followed later by auburn tool company. The stamps they used on the tools were very similar as well
I hadn't thought of toolmakers, Mainebill. I like the Dunham & McMaster mark that has the Auburn stamp with a period after it...a little unusual ending a stamp with a period. Do you know when these toolmakers were in business? Since all the known examples are on very early Large Cents, the issuer was probably in business early in the century. Dating the toolmaker's activity might point more strongly toward them. A slight difference in the styles are the edge of the depressions...serrated for the D & M stamp and straight for C-B-D 's example. It may not be significant though. Bruce
