1992 British pound with 1993 reverse [gelöst]

Hi All

I stumbled across a 1992 1 pound coin with the 1993 coat of arms reverse. All I can find on line is the 1992 reverse should have a tree. I know the coat of arms reverse was used in 1983 and 1993 but can’t find anything that says It was used in 1992.  Am I missing something? Pictured is both sides of the same coin

It'll be a fake. What's the edge like?

The edge milling is weak, although this is far from the worst I've seen with regard to fakes.

The counterfeiters didn't care much which reverse they used so mismatches are fairly common.

It’s a documented forgery
