I’d have been 12 in 1967 and 11 or 12 sounds about the age I’d have been searching. I used to stay at my nan’s in Seven Kings in the summer holidays and get bags from the bank nearly every day, mainly pennies, halfpennies and threepences, but sometimes sixpences or shillings Never found a 1918 or 1919KN, 1869, 1950, 1951 or 1953 penny or 1946, 1949, 1950 or 1951 threepence. Lots of pre-1947 silver, but hardly and pre-1920
I still have the albums. Mostly worn rubbish, but pretty nostalgic.
