Pre - decimal British coins: The old Penny, and the Sixpence (aka - the 'Tanner'). This was the old 'Imperial' coinage that we used before decimalisation in 1971. As well as these we had other coins coins with great names, like the Farthing (a quarter penny); Ha’penny (half penny); Thrip’ny (three penny); Bob (shilling: twelve pennies); Florin (two shillings)
UK old money in coins! On the left,- Farthing, Threepenny bit, sixpence. Middle,- halfpenny, shilling, florin. Right - Penny shilling, half crown. How much easier it was to work out decimal when the change over happened ~ I was still in Primary school. Funnily enough I still think in feet & inches and pounds & ounces though.
