Using acetone and immediately protecting the coin in a container like an Airtite will minimize atmospheric adsorbtion. Saturating the surface with water and allowing to &quot;dry&quot; in normal, humid, room air will re-equalibrate the metallic surface forming an even micro-layer of water molecules. </p><p><br /></p><p>Bottomline, why not play it safe and dehydrate with acetone and store the coin rather than playing russian roulette? I don&#039;t understand how anyone can argue my point.[/QUOTE]</p><p><br /></p>
