<p>[QUOTE=&quot;SuperDave, post: 2338558, member: 1892&quot;]MS70 has its&#039; place, used carefully, but as the gist of the explanations of it indicate, it is nearer the edge of being more intrusive than necessary. Only patience stands between the conservator of a coin and success with milder methods. That does not mean a collector learning to conserve should not become expert in its&#039; use; quite the opposite. On the (<b>mandatory</b>, IMO) scale of relative intrusion - and therefore greater risk to the coin - MS70 could reduce a process from three lesser steps to a single step, lowering the chances of a mistake.[/QUOTE]</p><p><br /></p>
