My dad and I pulled out his old coin collection just to see what he had. We would this quarter and upon using google, found that it is missing the clad side on the back. Also it may be just normal wear, but ts only around the very edge, it looks like it wasnt stamped right or something. Attached is a photo of the front and back of the coin, and the arrows point to where i believe it may have been offset during printing. Any ideas of its worth?
I don't see any off-center appearance, but it does look like an "open-face sandwich", with the obverse outer layer missing. It should be somewhat thinner than a regular quarter. For a value estimate, you should check with the folks at the Error World Club forum.
