I had them in the 60's and filled them with pennies and halfpennies collected from bank bags, but everything older than about George VI fell out every time I opened the things. They were basically useless. I never considered using sticking tape though! As King Kenny said, I would have bought them from WH Smith in Basildon town centre when it used to sell useful stuff. The rebranded TG Jones, which no longer sells anything anyone wants or can't buy cheaper elsewhere, is about to close, taking the town centre's Post Office with it. End of an era...
