<p>[QUOTE=&quot;UniqueDesigns, post: 2092324, member: 17654&quot;]What products do you who clean coins use? Are they different per metal?</p><p>If NCS were to conserve any coin, would they dip or use electrolysis?</p><p>I&#039;d think any dipping product would be a destructive process, where running electricity through pieces, using the same metal as the electrode on the + side would be non-destructive.</p><p>As for this OP&#039;s coin having color on only 1 side, wouldn&#039;t a book with paper backing the coins only allow the environment to only effect the side of any coin exposed to the atmosphere? So, any MS coin could be natural/clean on the protected side while toning as the OP&#039;s silver looks?[/QUOTE]</p><p><br /></p>
