That's one heck of a find! Think I found your coin! This likely dates to well before Columbus, so could be either from a lost collection, or Viking loot. It looks to be a medieval Enrique II 1369-1379.

WOW, if it could only talk! Outstanding find!
What an incredible find! It certainly gets a person's imagination working overtime. How did such a coin end up in the United States?
I had to Google "billon" as I had never heard of that before.
Billon is an alloy of a precious metal with a majority base metal content. It is used chiefly for making coins, medals, and token coins. The word comes from the French bille, which means "log".
How it the world would something like this make it to the fields of Central Virginia!!
Thank you, Digger!
