Looks like a late 16th/early 17th century coin called a parpagliola. Never heard of them before but most I can find online seem to have been struck in Milan though there seem to have been cruder copies struck elsewhere including mantua.
Here's an example: https://www.numisbids.com/n.php?p=lot&sid=708&lot=1172
If you google image parpagliola there's quite few similar to yours
Today i found this old coin. I'm sure that i've checked the area before but here is another.
First i had a ferrous sound but from a different angle i had also a 75.
First came out a rusty nail and after that the coin.
Can anyone help me identify it?
Thanks.
