Old money to decimal currency was a BIG com..
As a kid we used to get our pocket money and wander off to the sweet shop - one of my favs were the chocolate mice for 1/2d each.
so old money 20 bob x 12d =240 then x 2 (1/2d) so 480 mice to £1
wasn't long once decimal the mice were 1/2p each and losing 280 mice per £
Since then the mice just got smaller like Quality street tins and Toblerone/wagon wheels etc
The so called 'big purple one' is now more like the medium size purple one.
