[QUOTE="Oldhoopster, post: 4053155, member: 84179"]From your post "I would like to know what literature or past experience he is basing it on. Does he know for sure paint thinner will harm coins or is he just afraid of what it might do?" Are you serious? You think people are guessing? Depending what chemicals are in your paint thinner, they ABOSLUTELY can react with the metal in your coin. Some chemicals could break down into Hydrochloric acid, some chemicals remove toning by removing the metal on the surface of a coin. Some chemicals can leave a residue on a coin which can then react with environmental factors over time and cause damage. There are no short summaries to explain all the chemistry. If you don't trust the members here, then YOU need to start doing the searches, pulling the pieces together, and making your own conclusions. The information is out there, but it would be a lot of work to find all of this stuff and simplify it for the non-chemists, especially since the information provided to you has been well known for years.
