The florin was the currency of the British colonies and protectorates of East Africa between 1920 and 1921. It was divided into 100 cents. It replaced the rupee at par, and was replaced in turn by the shilling at a rate of 2 shillings = 1 florin. The florin was equivalent to 2 shillings sterling.
Coins
Because of its short period in existence, few of the coins minted were actually issued and are consequently scarce today. Coins were minted in denominations of 1, 5, 10, 25 and 50 cents and 1 florin but, according to the "Standard Catalog of World Coins" (C. L. Krause & C. Mishler, Krause Publications), the 50 cents coins were not released for circulation and only 30% of the 1, 5 and 10 cent coins produced were issued for circulation.
