<p>[QUOTE=&quot;ajwright, post: 131667, member: 5621&quot;]I recently found a silver coin with the inscription &quot;Continental Currency&quot; in the house of my grandfather (Pictured Below). And am looking for some more information on it.</p><p><br /></p><p>It appears to be pure silver, although the differences in thickness in different parts of the coin made it impossible for me to determine the exact volume and hence density (although I estimated it to be between 10.96 g/cm^3 and 8.04 g/cm^3, 10.4 g/cm^3 being pure silver).</p><p><br /></p><p>It weighs 105.8 grams, and has a diameter of approx 66 mm (Ranging from 65.1 mm to 67.3 mm depending on where it is measured), and a thickness of approx 3.1 mm (Ranging from 2.9 mm to 3.7 mm depending on where it is measured).</p><p><br /></p><p>It was heavily tarnished (black) when I found it, however I was able to clean it up using Galvanic Reduction.</p><p><br /></p><p>The photo below is a black and white photo of the front, back, and rim of the coin.</p><p><br /></p><p>Thanks for any help.</p><p><br /></p><p><img src="http://i55.photobucket.com/albums/g124/ajwright21/Coin.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
