Kinda of an interesting die stage, I don't look for foriegn coins they just find me. What kind of doubling do you see? She has what looks like die chips in the eye from nose to chin, and thru the lips, under the ear. Multiples probably 10 die chips that border the hair to the face. And a big mole on her neck. Too bad for the excess circulation.
I will have to remember that. I just don't hunt or see these coins very often. I thought it was die deterioration.
It is die deterioration - RM really works its dies these days. The number of minor (and not so minor) varieties to be found on the 2016-20 £1 coins is not to be believed.
So they are die chips or Interior die breaks and not just plating blisters? From the responses, I figured that it was mainly a plating issue.
I would describe it as 'die erosion' - from my understanding this is a die issue, and not a plating issue. Chips are also a common occurrence on 10 & 50ps of this vintage.
