This Mercury Dime is set in a gear like housing, it wood be interesting to see what is on the other side, however it is sealed over with very old and hard tar.
Definitely one of the more interesting mercs I've seen. I'm still amazed that you're digging green coins in our area this late into spring. You definitely have a nose for finding the low spots.
That's cool, man Zap that sucker. Perfect candidate for electrolysis. That stuff will flake right off of that... Here's a link on how to do it at home with almost nothing. http://gometaldetecting.com/electrolysis_cleaning.htm
(Kids ask Mom and Dad first)
