Pope Nicholas V: A Gold Ducat with His Coat of Arms
Vatican ducats were coined in the papal mint from the year 1432. They were coins of Venetian origin that circulated with the florin, which was worth 6 shillings at that time. In 1531 the florin was succeeded by the scudo, a piece of French origin (écu) that remained the monetary unit of the Papal States.
This particular ducat bears the coat of arms of Pope Nicholas V on the obverse side, with his name along the right side of the coin.
On the reverse side is an image of Pope St. Peter holding the cross keys, the symbol of the papacy.
