<p>[QUOTE=&quot;Conder101, post: 1909536, member: 66&quot;]Cotton or cotton cloth itself is too soft to scratch a coin, HOWEVER the troublemaker is dust.&nbsp; A significant amount of common household dust is silica, and silica IS harder than the coinage metal.&nbsp; The scratches &quot;caused&quot; by the cloth come from the cloth capturing the silica grains and dragging them across the coin like sandpaper.[/QUOTE]</p><p><br /></p>
