===Shillings and florins===
Shillings and florins, together with their same sized 5p and 10p coin equivalents, coexisted in circulation as valid currency until the early 1990s. In theory, this would have included coins dating back to 1816, but in practice, the oldest were dated 1947, as older coins contained silver, meaning the value of their metal was worth more than their nominal value. 

The coins were withdrawn when smaller 5p and 10p coins were introduced in 1990 and 1992 respectively. The demonetisation of the larger-size 50p in 1998 means that there are now no sterling coins in everyday circulation dated earlier than 1971.
