<p>[QUOTE="Pyrbob, post: 572879, member: 17044"]The new pic makes it look more like it is missing the clad layer on the reverse. What I meant before was coins can tone in the proof set cases so I thought maybe your quarter reverse was just toned and not an error. Clad coins including quarters have a copper core sandwiched between 2 layers of cladding on the outside. When one of the clad layers is missing before it is struck then the coin has one copper side. You confirm this by weighing the coin because it will be underweight. I can see where this is harder when it is one of the coins in a proof set. Also the coin will usually be a weak strike because of being thinner than normal. But proof coins are struck with a higher striking pressure so the strike might not be affected as much. This looks interesting and I would get it to an error specialist. I would suggest sending it to CONECA. The website is CONECAONLINE.ORG. Or take it to a major coin show if one is around you.[/QUOTE]</p><p><br /></p>
