I'm normally a lurker here, but seeing your post, I figured I'd make an account Seeing your find, all I can say is WOW! I've studied connecticut coppers for a little while, and as far as I know, there's no established die variety for a copper with two obverses. This means that you either have a rare error coin, or a contemporary counterfeit, both of which could be worth a lot of money. I'd definitely recommend getting your coin appraised, because this could honestly be a once in a lifetime find.
