When a coin is graded as being 'Lacquered' what does the term mean. Thanks

The term "laquered" usually pertains to old copper/bronze coins. An old-time method for patina preservation was to apply a thin layer of laquer to a coin, primarily to keep red/red-brown coins from turning brown. Laquer can usually be removed with an organic solvent, acetone will sometimes work but you may need a nonpolar solvent such as xylene.

Anybody know for sure whether xylene will discolor red copper?

Xylene will not affect copper, otherwise I would not have recommended it  However, the patination may look funky if there are breaks in the laquer coating. There is the possibility of ending up with a red coin that has odd brown areas or streaks but a coin coated in laquer isn't really eye appealing either. |

My reason for asking is that I have a coin that is in the MS-65 or 66 range and 100% red. It was previously lacquered and almost all was recently removed with acetone. The color was unaffected, but a few persistent tiny spots of lacquer remain. I was thinking of trying zylene on them, but I am somewhat a wussy about trying it on a potential $4K coin.

NCS removes professionally lacquer.If your coins is so high grade then you must sent it to professionals.

Soak it in Xylene for 30 minutes, then overnight in Olive Oil, then repeat.
I never gave you that kind of advise.... >>>> : 0 : )

I didn't know acetone & xylene would remove lacquer. I sold a 1909-s vdb to the local coin shop that we believe was lacquered. He said he was tempted to crack it from the slab to try resubmitting it. Didn't know it might be as easy as an acetone soak.

This looks like a task for NCS. While I have never sent them a lacquered coin, I have used them for key date bronze coins with surface debris, and was very pleased with the results. Both of the coins that I sent in were successfully "conserved" then crossed over to NGC for grading as problem-free coins. The only drawback that I can see for you is that NGC does not seem to be held in high regard by Canadian collectors.
That is a gorgeous coin, and well worth sending in. Nice uncirculated Maritime Provincial coins are quite hard to find.

Nice coin bosox. If this is the coin, you may want to talk to NCS. I am by no means a coin-Doctor. I just know what has worked for others.
Great luck with it. and again, great looking coin.
