I have just recieved my pocket money, and i noticed that one of the £1 coins stood out from the others...firstly, it has the welsh dragon on it (which is wrong for its year), secondly, if i look at it closely i can see an incuse outline of the queens head on the reverse and an incuse outline of the dragon on the obverse...the DECUS ET TUTAMEN is correct exept that the top of the letters are towards the obverse not the reverse as are other 1991 £ coins...the ONE POUND below the dragon is somewhat double-struck (appears bolder than usual)... Is this confirmed as a fake, or is it just the mints mistake (very unlikely)?
