Hi all, dug this button in Cherry Hill, NJ. Front is toast with no details left, but the back still has a few stamped marks that I haven’t seen on a button before now. Judging by the shank, it appears to date to the early 19th century. Under the shank is stamped “CO” assuming company, the outer edge is stamped with letters inside a circle, possibly up to 9 letters as well as stamped or engraved lettering. Stamped/circled letters that I can make out are R(?) E P I T ? ? ? ?.
I figured this could be enough to go off of for one of you oldheads who have dug a thousand of these to possibly identify.
