A friend of mine calls it her copper pot. I suspect most of us have one but may not know it under that name. It is the receptacle into which brown, very low value coins are thrown in order to reduce the weight in trouser pockets, purses and the like. I have one and it receives all 1p, 2p and 5p coins that end up in my possession. (As it happens, I also have a jar into which I place £2 coins that I remove from circulation - but that is a different matter.)
A few days ago, I counted the contents of my copper pot. It contained more than £20. My original plan had been to bag the coins appropriately and pay them into my bank account whenever I deposited a cheque. But cheques are now very thin on the ground.
Some supermarkets have machines that accept, count and refund the coins thrown into them - but then claim perhaps 10% of the value of the coins for doing this.
I then hit upon a cunning plan.
Usually, when shopping at a supermarket I pay using my debit card - contactless. Isn't technology wonderful? Alternatively, in Tesco, I use Tesco pay. which, using an app on my iPhone amounts to the same thing. On my last visit to Tesco I took £1 in 1p coins instead. I bought only a few items and used the self-serve checkout. I surreptitiously poured the bag of minuscule coins into the funnel and waited. It accepted the coins and so I inserted a fiver to pay the balance. I did receive a couple of small value coins in the change - but that is a small price to pay.
I can possibly empty my copper pot in a couple of months ...
