Some kind of silver hammered coin... what is it?

Came across this coin today. Can anyone ID it? Any particular value? Right around the size of a U.S. dime. Thanks for any help you can provide!

Looks like a denaro from Genoa circa 1139-1339. In that condition, probably not worth more than $10, but still interesting.
Here's mine, which is still fairly crude:

Awesome, thank you! Your coin is crisp!
