1982 revised inscription

The 50p joined the 5p (shilling) and 10p (florin) coins in circulation. It was introduced to circulate alongside its equivalent; the ten shilling note. The reverse design of Britannia by Christopher Ironside was traditional, but the heptagonical shape of the coin was revolutionary and at the time was the only such coin in circulation in the world. The edges were rounded to ensure that the distance across the coin was a constant 30mm so vending machines would accept them.
