I basically take a regular isopropyl alcohol pad, allow it to dry out and dip it in 96% (192 proof) pure neutral grain spirits. I apply light to moderate pressure to the fields and then do minute detailing around lettering and design elements with a bendable plastic toothpick through the alcohol pad. I typically don't see any hairlines on the coin afterward, even at 20x magnification.</p><p>Now I'm not suggesting anyone else try this on their coin, especially one that you really like and/or has decent value.</p><p><br /></p><p>PS: Cotton gloves will cause hairlines the same as your shirt if you rub the coin with them on.
