Good day all. I found this artifact on a town green along with coins dating back to 1873 in the same area with the equinox. It had a vdi of 15-16. And appears to be lead. At first, before I cleaned it I thought I may have a counterfeit since I have seen a few that were similar composition and had a similar rim near the edge but the ones I saw had the same details/strike as a coin. I couldn't make out any details on this one other that the indentations that don't go all the way through. Any ID'ers out there ?

Could it be part of a merchant set for weighing coins to see if they've been tampered with?
