UK 20 pence 1983 does not look right is it a poof

I have this 20 pence 1983 and looks frosted

  What do you think?
  Thank you daryl

You know i really like the pic of QE2. The shadows on it came out very nice

Possibly.

Which leads to a question I am frequently asked on my stall. How do proof coins get into common circulation?

One answer, which I know to be correct, is that here in Southampton and probably the rest of the UK we have a lot of drug addicts who break into houses, finding proof coin sets they smash them open and circulate them because to them a 20p or 50p or £5 coin is just a 20p, 50p or £5 coin.

So do not be overly surprised to find proof coins in your British change

I also think it is a proof.

Thanks you guys . Matt that is sad, but we have the same problem here. Thats the second UK coin i have found from proof or sets.  I also have a UK 5 pence 1990 large from a set. Thank you both again yours daryl

sometimes people just buy those sets for only one coin. rest will be used in circulation.

I bet a lot of kids get proof sets as gifts and they turn them into sweety money.
