I've got 2 of these at the moment, and there maybe more in the baby "cash jar" at home
When I go to the shop to get cigarettes at 4.80 a pack - I put the 20p change I get from a fiver into the jar without too much thought.
As soon as I heard this yesterday I shook the jar upside down to see if any came out and guess what, I found 2 undated coins straight away.
I know there are another 60 20p coins in there
at least so I'll be smashing the jar (it's a cutie "my first baby ceramic jar which needs smashing once filled) and filtering through all the shrapnel to get the rest of the silver out
