That coin was issued by Bartolemeo Gradenigo (GRADOMICO on the obverse from 8 to 10 o'clock), AD 1339 to 1342.
Thanks John. I did the best I could and I appreciate the correction. It’s older than I thought. That’s nice.
That's a nice one @Collecting Nut I picked up one earlier this year that was your coin's predecessor, though not as nice as yours: Francesco Dandolo Venice 1329-1339 AD AR Grosso Obverse: FRA DANDVLO D/V/X - S M VENETI, Staint Mark standing right holding book of gospels in left hand and banner in right, Doge standing left holding banner Reverse: IC-XC, Christ the redeemer enthroned holding book of gospels, annulet in folds left foot
