Venice Doge Lorenzo Prioli

Please help me evaluate. Coin Soldi . Weight 1.03 grams.

Lorenzo Priuli 4 soldi coin.   Initials LM 

Here is an auction sale from a few years ago of a similar coin:  https://www.numisbids.com/n.php?p=lot&sid=2563&lot=441

Yours has less wear, but the uneven corrosion (or whatever the black material is) detracts from the appearaonce, so I expect the value is lower.

Огромное спасибо!!!
