Spanish Silver

[Gunrunner61]

Found this piece in 2003, I'm just wondering if it's real or counterfeit.I do know a little history on the place where it was found, General Andrew Pickens built the house in the early 1800's and it burnt to the ground about 15-20 years later. For size Diameter 39.69 Weight 18.8 grms.Any help appreciated.

A bit of a heart break but still a killer save!
