<p>[QUOTE="Boss, post: 519607, member: 15110"]Well Doug, I hear what your saying, and glad you can agree oil can protect coins. It does not chemically alter the surface (there is not a chemical exchange of ions or breaking of chemical bonds except to degrade grime and verdigris). Can be removed with acetone or xylene (pure acetone does not change the coin- unless it's not pure. Most all collectors agree on that, and you yourslef (Doug) have given detailed instruction on how to do so- 3 dishes of acetone and a final rinse with distilled water. Most collectors don't believe this harms the coin in anyway and can remove recent finger prints and PVC damage. </p><p><br /></p><p>Cloudsweeper: Look under "Post some Lincolns" last few pages at my 1915-it has a lot of mineral oil on it. I will post some coins perhaps before and after mineral oil later on. Also it's on my profile page.[/QUOTE]</p><p><br /></p>
