Opening the post earlier this week I noticed an amazing example of 'waste not want not'. As the half-penny ceased to be legal tender in this country in 1984 (twenty-five years ago!) these stamps had to pre-date that time. In fact they were part of the Christmas set (the first class stamp). I'm amazed that somebody managed to hold on to these for twenty-five years and then use two of them together to form current first class postage tariff!
