Had a little time to kill today, went for a short hunt on my property. (House built in 1840) Only a few targets, and this is one of them. Clipped, Copper, and just a shade larger than a US Quarter. Thanks for any help you can offer. Now to figure out how to post a pic. from my USB microscope. I can only make out "UN" on the center of the reverse.
