<p>[QUOTE=&quot;Insider, post: 2352545, member: 24314&quot;]Do as Paul says...don&#039;t touch it.&nbsp; The black spots have eaten into the surface.&nbsp; Nevertheless, NCS could make this coin presentable enough to sell but it would take several treatments and about 20 minutes of work partly done using a stereo microscope!. </p><p>&nbsp;</p><p>You can always trade it plus a little extra cash for a slabbed Eagle.</p><p>&nbsp;</p><p>Or, here is a tease.&nbsp; I first wrote full directions for you as this is a great coin to practice conservation on.&nbsp; It has several common characteristics found on silver &quot;gone bad.&quot;&nbsp; There is light toning, semi-dark toning, and corrosion spots.&nbsp; Plus, even if you were to screw it up, it&#039;s always worth melt.&nbsp; Then I decided it was too much to tell and deleted much of it.&nbsp; Sorry about that - really.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" />.&nbsp; I don&#039;t want anyone ruining their coins. </p><p>&nbsp;</p><p>However, it did take me almost forty minutes to type specific directions and chemicals to use and I couldn&#039;t bring myself to waste all that time for nothing...so, in the spirit of education, I&#039;ll run down the typical conservation steps on a coin such as yours, leaving out important details and /methods.&nbsp; Besides, all this is available with some research or over beer with a group of conservators at a seminar. </p><p>&nbsp;</p><p>Conservation labs use deionized water, heated ultrasonic cleaners, fume hoods, gloves, goggles, and proprietary chemicals.&nbsp; Other off-the-shelf products include things such as hydrogen peroxide, MS-70, medical grade acetone, distilled water, baking soda, toothpicks, and acid dips.&nbsp; </p><p>&nbsp;</p><p>For Silver Coins:</p><p>&nbsp;</p><p>A. PREPARE THE SURFACES</p><p>&nbsp;</p><p>1. Clean surface w/acetone.</p><p>2. Clean w/hot MS-70 to remove as much surface toning as you can.</p><p><span style="color: #000000">3. Make a liquid paste of ...&nbsp; You will need to remove the spots first using... Then gently clean the surfaces until they are bare silver with no black remaining (if you are experienced doing this, the coin will not be hairlined). </span></p><p>&nbsp;</p><p><span style="color: #000000">B. DIP THE COIN</span></p><p>&nbsp;</p><p><span style="color: #000000">1. Dip coin in an acid dip.</span></p><p><span style="color: #000000">2. Neutralize w/baking soda solution.</span></p><p><span style="color: #000000">3. Rinse with distilled water.</span></p><p><span style="color: #000000">4. Dip in acetone.</span></p><p>&nbsp;</p><p><span style="color: #000000">C. DRY THE COIN</span></p><p>&nbsp;</p><p><span style="color: #000000">1. Dry using hot air or compressed air.</span></p><p><span style="color: #000000">2. Seal the coin immediately.&nbsp;&nbsp; </span></p><p>&nbsp;</p><p><span style="color: #000000">If conserved correctly, your coin will be lustrous silver with enough eye appeal to sell because 95% percent of the dealers/collectors will not have a clue that the coin is not 100% original! <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie12" alt="o_O" unselectable="on" unselectable="on" /></span> </p><p>&nbsp;</p><p><span style="color: #b30000">I am posting what&#039;s left of this now and I will not respond to any questions, discussions, or critiques concerning what I have written.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie66" alt=":muted:" unselectable="on" unselectable="on" />&nbsp; </span>[/QUOTE]</p><p><br /></p>
