<p>[QUOTE="rlm's cents, post: 292258, member: 7957"]I have no idea what the problem is with the bent/warped coins, but I am guessing that they are so fouled that he cannot tell what is silver and what is not. Franklins, liberty and Morgans are silver - no problem. As to the Kennedy's, I would start with vinegar and see if that works. Another trial might be ammonia. Maybe one after the other. As a last resort - <span style="color: Red">IF YOU ARE FAMILIAR WITH WORKING WITH ACIDS</span> - try hydrochloric acid. Use it VERY dilute acid. It will remove an equivalent amount of metal. All you should need is enough color (these will not alter the color of silver) to determine if it is silver. If your dealer will not take it that way, try another. As stated above, all you are going for is bullion vale.[/QUOTE]</p><p><br /></p>
