Removing laquer from coins

[svenska]

I've just purchased a number of George VI specimen sets at auction. They are mostly 1951 and 1950 year sets and the majority of coins including the 1950 and 1951 pennies are in uncirculated condition. The thing is - they have been coated with a thin layer of laquer. I'm aware that this could be removed (following all the health and safety advice) with acetone. Does any one of forum members have experience of using this method and would it affect the full lustre of the copper coins?

Thanks

I have used acetone on silver coins, not sure why they had nail polish on them - but they were essentially just melt value coins. I have used on cheaper pennies too, but never anything expensive.

I have had mixed results on copper/bronze, it depends on how thick and what type of lacquer is used, I have had best results with the coins where the lacquer is even and thinly applied, but it really is a case of luck!!

Cellulose thinners works on most lacquer, just be sure that it contains xylene and toluene, neither of which should harm your coin.

A point very well made. I have access to a pro paint shop with fans and filters and tend to forget that there are hazards in home use. Apologies.
