Title: pvc removal
Post by: trout on May 14, 2015, 04:10:17 AM
I had a few coins come back "pvc residue" boddybags  and thought what the hell I'll have a crack at getting rid of the pvc.
I soaked the coins for a few days in acetone and it worked a treat.

these are the coins I did.

all NZ 1953 proofs which came back from PCGS graded at
 
3d PR64CA
6d PR64+CA
shilling PR65CA
florin PR65CA  
half crown PR64CA  
crown PR63CA  

So if you do the acetone thing carefully you can get the desired results :)

Woow that's awesome. Any good beginners article on how to perform CPR on PVC-ed coins with acetone?

Don't know of any good articles but a tip; use a lidded container (make sure it is acetone resistant first) otherwise the acetone evaporates rather quickly.

did you touch the surface of the coins Trout?

or just soak and let them air dry off?

Just soaked it off and ran some fresh acetone over the coin to finish it off.
