There's time yet to spend the paper £20 & £50.

Lot's of the rest will be in jars, piggybanks, pockets etc - or even down the back of the sofa.

In people's safes, safety deposit boxes, under mattresses, in unused handbags and wallets, behind the wardrobe.

When my elderly neighbour I was her executor and we found nearly £200k hidden in plastic carrier bags in her wardrobes. She had lived a very modest life claiming every benefit available.
I doubt she's the only one.

I must confess I put one of the old pound coins underneath my kitchen floor when I tiled it about thirty years ago :-)

It's all stuffed in that mattress I accidentally took to the tip!
