Why low-value coins should stay in circulation

SIR – Christopher G Knight (Letters, January 26) thinks it is time to stop producing all coins below the value of 20p. However, I recently paid £1.19 for an item in a shop, so handed the assistant £5. When she struggled to give me change, I suggested that I give her an extra 20p, so she could give me £4 and a penny change, which she found much easier. I think there is still a place for lesser value coins.
