By the 1950s, coins of Kings George III, George IV and William IV had disappeared from circulation, but coins (at least the penny) bearing the head of every British king or queen from Queen Victoria onwards could be found in circulation. Silver coins were replaced by those in cupro-nickel in 1947, and by the 1960s the silver coins were rarely seen. Silver/cupro-nickel shillings (from any period after 1816) and florins (2 shillings) remained legal tender after decimalisation (as 5p and 10p respectively) until 1990 and 1993 respectively, but are now officially demonetised.
