I've just noticed that I have several 1992 10p coins that are thinner than 10p coins of other dates.
Is this normal?
Two are obverse 1 - L of ELIZABETH points to a space and I think reverse A- 1 of 10 points to a dot.
The weight varies between 6.48 grams and 6.58 grams.
The Royal Mint specification is 6.5 grams.
