<p>[QUOTE=&quot;Conder101, post: 3987348, member: 66&quot;]The edge picture suggests what happened here. Note the reeding is strong and clear, but only on the copper layer.&nbsp; It is weak to non-existent on the clad layers.</p><p><br /></p><p>This was an acid soaked quarter.&nbsp; The acid ate away at the copper reducing its diameter, but retaining the reeding pattern.&nbsp; Then the coin circulate and probably passed through a LOT of vending machines.&nbsp; This has worn away the reeding on the clad layers but the reeding on the copper was protected by the overhanging clad layers.&nbsp; The clad layers have now been worn or beaten down to nearly the same level as the copper, but I think the copper is still recessed a little.&nbsp; The reduction by the acid also results in the odd sound.[/QUOTE]</p><p><br /></p>
