I think when I was a kid you could still buy sweets for a penny each. We do like playing the 2p machines when we're at the seaside, but 1p coins are almost useless. I did get rid of some in the machine at the supermarket, but they take a cut. I think some people use them for the self-scan to pay part of the cost and do the rest by card. I have a pot of assorted coins in the bedroom, but it doesn't seem to go down.
