Almost everyone knows that Olive Oils are man made and vary from batch to batch and manufacturer to manufacturer. This makes it so some may damage a coin due to excessive acidity. Also, when using it there is now a residue of oils on the coin that must be removed also. Your best bet is to start with just Distilled water. Or Acetone and then distilled water. Use the search tab at the top for such previous posts about Acetone, cleaning coins, etc. Also, eventually Thad will jump in on this one. Report this Post to the Staff
BadThad Bedrock of the Community United States 19942 Posts	Posted 04/11/2012 6:15 pm Welcome to CC! VERDI-CARE would help it some, but not completely. You should try a soak in distilled water and then chip away at the big chunks of verdigris with a toothpick (while under water). Take it out, rinse with acetone and then put it into a holder. IMO, the coin shouldn't be messed with because, other than the large spots of verdigris, it looks like it should for it's age. I agree with Carl, NEVER use olive oil on a coin. The acids act to damage the surface and it cannot be fully removed without using xylene. Oil in general should NEVER be used on coins, I don't care if it's Coin Care or Blue Ribbon....oils are BAD.
