The Florentine florin was a gold coin (in Italian Fiorino d'oro) struck from 1252 to 1533 with no significant change in its design or metal content standard during that time.[1] It had 54 grains (3.499 grams, 0.1125 troy ounces) of nominally pure or 'fine' gold[2] with a purchasing power difficult to estimate (and variable) but ranging according to social grouping and perspective from approximately 140 to 1,000 modern US dollars. The name of the coin comes from the Giglio bottonato (it), the floral emblem of the city, which is represented at the head of the coin.[3]
