Thanks yeah the coin is a Sicilian one and has some weight to it. View attachment 653111
I agree. Silver coins that old are not shiny, and genuine ones are very thin.Don't feel too good about it. Silver coins that old don't really look like they have shiny silver plating, such as that one. These things are just faked so much.... and like I said if there was nothing else of a significant nature in your inheritance it's easy to see the direction this could take.
Can you post a picture of the edge. The genuine ones are very thin, and cast fakes usually on the thick side. Also weigh it if you have a scale.
