Dull Coins After Acetone Bath

I have examples of Canadian small cent George VI specimen strikes, in PCGS holders (no less) and within 5 seconds of looking at the coin, I knew it was acetone soaked. Specimen strikes are different animals though, the surfaces of those fields are like mirrors (equivalent to early US proof strikes of 1-cent coins)... the effect on the mirror fields leaves a "gasoline on water" appearance to the coin's mirror surfaces, and halos around the devices.

I have a few examples in my collection, including a 1950 specimen strike that became a "sacrificial lamb". I'll try to remember and post a few photos later this week.

^ If they detect it, they will return it as non-gradable, as it could deteriorate further in the slab. I got taken this way once 20 years ago with a nice, glossy large cent that a quick acetone dip revealed hidden green in the recesses.

Of course. I'll post an update later this week.

Well, I couldn't really get rid of the dullness but it became much less visible after a few additional baths which is good. It's not perfect but it means the hunt for te perfect example is still on :)

Thanks for the wonderfull insights and tips.

Really love this community!
