We found several of these vintage solid brass coins at a flea market and many of them had small stamped numbers. We think they were used as hotel room key markers or tool tags back in the day.
For something with an industrial history, we couldn't get over how delicate the stamped border was so we re-purposed this coin to be worn as a reminder that beauty is in the eye of the beholder.
