1 lira 1794 Republic of Genoa [решено]

Hi, i have recently got this coin, but i have the doubt it is a fake.
Some one have experience on that? Thank you for your help.

Just from looking at the pictures it looks good but quite certain you can see at top and bottom that there are removed traces of it previously being attached to a jewelry piece.
This of course depreciate its value quite a bit.

It's clearly silver and real, you can see some dents into the silver, which reveals more silver , so...it's silver :)

It is almost 3 mm smaller than the declared diameter. This is the reason i thought to a fake

I found out, in Corpus Nummorum Italicorum catalog, that the 1794 issue is only 23 mm diameter.
It isn't remarked in numista page.

This is the reference: CNI vol. III, page 496, coin n.8.
