At the link below are some somewhat similar coins. Anyways, welcome to TNET Johnbikes! We hope you will tarry with us and share some treasure hunting stories and pics of finds!
Looks kinda like a Brasher Dabloon “Lima Style” perhaps. 1742 dates but actually struck in 1786. Very very similar in design but prior to Brasher working with gold. Also kinda looks like a J. Charmers design. He was a Silversmith in Maryland in the 1780’s... Annapolis. 1783 SixPence?...
