A 15th century Florin is an Italian coin. A Florin was never used in Germany. The monetary equivalent of a Florin in today's U.S. dollar is about 200.

The currency in Italy is Euro and its code is EUR.

Before the Euro they had the Italian Lira.

There was never a 2 Florin coin minted in the 20th century.

The first British Florin was issued in 1849, so it is unlikely that there would be a Half Florin coin minted any earlier.

There was never a British coin called a Half Florin. If one existed, a Half Florin would be One Shilling.

Such a coin does not exist.

The first British Florin was introduced into circulation in 1849.
