From the reference box #64
#64 - Banking Money bags/pockets for Barclays Bank Ltd., Lloyds Bank Ltd. and Midland Bank Ltd. (now HSBC). I picked these up at the weekend from a local flea market. They came in a bundle with a few of each one, most of which are unused.
I think they're from the early 70's as here in the UK we went decimal in 1971, losing the pound, shilling and pence in favour of just pounds and pence with an 18 month change-over period. This bundle of bags includes both decimal and pre-decimal nominations so I'm guessing they are from this change-over period.
The little 25p one at the bottom is my favourite, partly becasue of the big, thick black number 25 and partly because I miss 1/2 pence pieces!
