<p>[QUOTE=&quot;The_Cave_Troll, post: 116332, member: 1674&quot;]I obviously haven&#039;t seen the picture yet, but it is VERY likely that this coin is plated with silver, zinc, or mercury.&nbsp; All 3 can be easily done and the first 2 are routinely done as high school chemistry experiments.</p><p><br /></p><p>The first diagnostic to see if it really is plated is to weigh it.&nbsp; Take it to a jeweler and have it weighed to the nearest 1/100 of a gram.&nbsp; If it is in the 3.05-3.15 grams range it is plated.&nbsp; if it is more or less than that then it is possible that it is an off metal strike, in which case more testing would need to be done.</p><p><br /></p><p>I expect the weight to confirm that it is plated, though.[/QUOTE]</p><p><br /></p>
