In my change after shopping, I discovered a 50p coin that seemed, and was bigger than another one. The larger one has the number 50 and 'NEW PENCE round the Britannia side of the coin and is dated 1969. A smaller, 1997 50p coin has just FIFTY PENCE on the coin. Was the 1969 one just a trial run for decimalisation in 1970 and was it ever legal tender? Does any one have an answer? thanks in advance
You must have been very much in love around the end of 1997. I can't think of any other reason why you could have failed to notice that the new 50p pieces, issued from 1st September onwards, were smaller than the previous ones!
by the way - Royal Mint coins never lose their value. Demonetised coins may be exchanged at face value for current coins provided at least £1 worth of such coins are offered. So all you have to do now is find another one.
