<p>[QUOTE=&quot;Insider, post: 2426608, member: 24314&quot;]Sorry you posted this as you are totally misinformed about MS-70 and how to conserve a coin properly!<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie46" alt=":facepalm:" unselectable="on" unselectable="on" /> I was going to stay <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie66" alt=":muted:" unselectable="on" unselectable="on" /> on this except for my initial post but I fear your methods are going to get a lot of coins ruined and hairlined.</p><p>&nbsp;</p><p>Here is what I have learned from professionals in the conservation business.&nbsp; Hopefully the chemists on CT will educate you and I more.</p><p>1. You NEVER dip a coin in EZest as a <span style="color: #b30000">first step</span> in conservation.</p><p>2. You should NEVER USE tap water.</p><p>3. You NEVER dry a coin with a paper product or by patting it with anything.</p><p>&nbsp;</p><p>That should cover it except for this:&nbsp; Some large US silver commemoratives &quot;blow-up&quot; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie12" alt="o_O" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie15" alt=":arghh:" unselectable="on" unselectable="on" /> and become permanently stained (even though most of the haze disappears) when any of the usual conservation chemicals are used. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" /></p><p>&nbsp;</p><p>As of last week, the professionals <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie16" alt=":artist:" unselectable="on" unselectable="on" /> doing the work that I speak with STILL do not know how/why this happens to some commemoratives that look like an easy and quick conservation job..[/QUOTE]</p><p><br /></p>
