<p>[QUOTE="Conder101, post: 144873, member: 66"]It could be a case of the copper nickel layer being scraped down and covering the copper on the edge. That does happen. (It happens in the blanking process though, not in the striking like Speedy suggested.) Much more likely is that it have simply been plated. Your dealer was wrong when he said that a plating layer would weaken the fine detail. The thickness of the plating layer they do on those things is in the neighborhood of .00005 inches - 5 hundred thousandths of an inch or about a tenth the thickness of the copper plating on a modern cent. A plating layer that thin won't have any effect on the fine details.</p><p><br /></p><p>The real key is the weight of the coin and THAT should have been the first thing that your dealer should have checked if he knew anything about error coins, which he obviously doesn't. (So anything he told you about the coin can be rejected, he doesn't know what he is talking about.) Weight the coin. If it weighs 5.67 grams +/- .23 grams then it is a plated regular quarter. (The weight of the plating is so small, about .005 grams. that it can just be ignored.) If the weight is 6.25 +/- .19 grams THEN it is a silver quarter.[/QUOTE]</p><p><br /></p>
