Thanks wheezydog as here is what I found as I believe this is Venetian. Seems these are common.
Giovanni Dandolo (1280-89)
48th Doge
AR Grosso, 19mm, 2.18gr. Obv: IO.DANDVL'.SM.VENETI, central Doge (L) and St. Mark. Rev: Christ enthrones. Paolucci, p.23, rarity: common. Numismatically, it was during these these years (1282) that the gold ducat was introduced. It was to be issued virtually unchanged by the succeeding 73 Doges.
The times: In spite of the strains on the economic system during the 14th C, this was a time of relative prosperity for Venice. It was to become more conflicted in the next decade, when the fighting with Genoa intensified. The Venetians were defeated at Laiazzo in 1294 and at Curzola in 1298. The phase of the war ended with the Treaty of Milan in 1299.
