<p>[QUOTE="medoraman, post: 1631188, member: 26302"]Cabinets usually do not have as much moisture around to let it go that far, but it can happen. I have seen some from the SE that were bad, but I believe the cabinet had been moved to a basement since the cabinet was in rough shape too. </p><p><br /></p><p>As for black being stable, my opinion would be no. It goes from glossy black to matte black, and the corrosion continues until theoretically the coin is completely corroded and all natural silver is converted. Stable toning can only exist if you have taken away the precipitating toning agents. Like others point out, wood will naturally over time lower its emissions, so in a cabinet it can start out badly for the coin, but get better over time. Put that same cabinet in a high moisture situation, though, and the coins will continue to deteriorate.[/QUOTE]</p><p><br /></p>
