I always wanted a Venetian Ducat and now I have one:
Venice Ducat of Doge Pasquale Cicogna 1585-1595
Obverse: Left Saint Mark, standing and facing right with banner, right, the Doge kneeling
S M VENET DVX PASC CICON
("Sacra Moneta Venetiae Dux Paschalis Ciconia" or "Sacred Money of Venice Duke Pasquale Cicogna")
Reverse: Christ standing with Book of Gospels, surrounded by 19 stars and oval
SIT T XPE DAT QTV REGIS ISTE DVCAT
("Sit tibi, Christe, datus, quem tu regis, iste ducatus" or "To Thee, O'Christ, is Dedicated, Which Thou Rulest, this Duchy")
Catalog: Friedberg Gold Coins of the World
Specs: 20mm, 3.50gm
These coins were made of 99% gold but sometimes had small amounts of impurities.
This particular coin has a corrosion spot due to exposed silver or copper on the surface.
Doge Pasquale became known for throwing out silver coins rather than gold coins during his coronation.
