<p>[QUOTE=&quot;Alexthegreat, post: 24766511, member: 101547&quot;]Hello guys,</p><p>I post this in the Ancient Coins forum because it&#039;s rather a question of conservation. I bought a German taler that was probably in the earth for a long time. The coin looks quite fresh, but maybe chlorargyrite and corrosion are issues.</p><p>I cleaned it in an ultrasonic bath with hot soapy water for a while, but the result was minor.</p><p>These coins were minted in Goslar as propaganda for a Protestant alliance between Hesse-Cassel and Saxony.</p><p><br /></p><p>The alloy should be almost pure silver. Are there serious ideas for further conservation or experiences with NGS, the conservation service of NGC?</p><p><br /></p><p>Thank you in advice and greetings from Germany</p><p><br /></p><p>Alex</p><p><br /></p><p><br /></p><p>[ATTACH=full]1584277[/ATTACH] [ATTACH=full]1584278[/ATTACH] [ATTACH=full]1584279[/ATTACH] [ATTACH=full]1584280[/ATTACH] [ATTACH=full]1584281[/ATTACH] [ATTACH=full]1584277[/ATTACH] [ATTACH=full]1584278[/ATTACH] [ATTACH=full]1584279[/ATTACH] [ATTACH=full]1584280[/ATTACH] [ATTACH=full]1584281[/ATTACH][/QUOTE]</p><p><br /></p>
