Fifty years ago today, Britain and Ireland said goodbye to pounds, shillings and pence and welcomed decimal money. From 15 February 1971, there would be 100 pence in a pound, rather than 12 shillings. That changeover decimal day in Britain was billed as D Day, no doubt a deliberate echo of the the D Day landings during the war, less than 27 years before.

I’m sure the decimal revolution was a wrench for my grandmothers, who grew up with Queen Victoria’s head on the nation’s coins. For me, it was a relief: as a seven year old, it meant an end to painful school maths lessons adding up in old money. But I still feel nostalgic for that lost world.

I grew up on old money, but was aware that change was on the way. Not long before decimalisation, my great aunt Megan offered my a choice: I could have my pocket money as a 10 shilling note or a 50p piece. I had never seen a 50p piece so went for that. Looking back, it was very generous regardless of the option I went for.
