<p>[QUOTE=&quot;medoraman, post: 1371524, member: 26302&quot;]If someone wanted to practice conserving coins, at least this would be a throwaway. Since its bronze, I would use a sharpened piece of brass and a microscope. After following Thad&#039;s great advice, physically remove the remaining verdigris with the brass pick. Only way to TRULY stop it. If someone was really good, you could try steel but have a much higher chance of damaging the surface with an errant cut. Ancient collectors get used to having to do this on certain coins. Short of that, Thad gave you great advice on how to deal with it.</p><p><br /></p><p>Chris</p><p><br /></p><p>Btw this is another method, and you can save the toning. Physically removing the verdigris is always an option, though either way your coin will always be damaged.[/QUOTE]</p><p><br /></p>
