Florin Gold Monetary Standard

Timeline

1. 1252–1350Republic of Florence · ItalyIn 1252, Florence minted a gold florin of standard weight 3.536 grams and 24-carat purity, with a lily (the city's emblem) on the obverse and St. John the Baptist on the reverse. Its stable fineness and weight quickly won the trust of European commercial society, becoming the standard currency for large transactions and international settlement.
2. 1397–1494Florence; branches of the Medici Bank · ItalyIn 1397, the Medici family founded the Banco dei Medici, with the florin as its core currency, establishing branches in Venice, Genoa, Lyon, Bruges, London, and elsewhere through bills of exchange and remote account systems. Between 1451 and 1460, the Medici Bank was at the height of its influence (under Cosimo de' Medici), and the florin standard provided a solid foundation for its transnational financial operations.
3. 1451–1460Major European trading cities · EuropeOver these ten years, the florin (including imitative issues from Hungary, the Rhineland, and elsewhere) had become the de facto standard for European international trade settlement. After the Ottomans captured Constantinople in 1453, the florin's role on Near East trade routes became even more prominent. During this period the Medici Bank maintained important financial services for the papal finances, and the florin was the benchmark currency for papal tax remittances.
4. c. 1500–1600Europe · EuropeWith the massive influx of American silver into Europe in the 16th century, bimetallism and later the silver standard gradually displaced the florin system's dominance. However, the principles of currency standardization, fiduciary money, and bill-of-exchange settlement established by the florin profoundly influenced the Amsterdam Wisselbank (1609) and even the formation of modern central banking.
