Crazia
The crazia, plural crazie (from the German: Kreuzer),[1] was an alloy coin with a value of 5 quattrini issued from the reign of Cosimo I de' Medici, first Grand Duke of Tuscany (1537 - 1574), onwards.It was imitated by the Duchy of Urbino, the Cybo-Malaspina family at Massa, and the Appiani and Ludovisi families in the Principality of Piombino.[2][1] An alloy coin of two crazie to the value of 10 quattrini was still being issued in the Grand Duchy of Tuscany under Leopold II (1765-1790), Ferdinand III in 1801 and Louis I of Etruria in 1802.After this date it was replaced by the 10 quattrini coin.[2][1] Later in the 19th century Tuscan postage stamps were issued in various values of crazie.
