Ah Ha! Thanks Purple Penny - As I suspected, PMD rather than an error... I would have thought that the acetone would leave some trace or damage to the shiny parts of the coin on the silver 1/2oz, but as I am not a metallurgist I don't really have a clue, but if someone said to be that I could soak a silver coin in acetone for several hours and it would not get damaged I would be very tempted to give them pretty good odds against... there you go, I learnt something today so it is a great day already - thanks again Purple Penny.
