I have 4 State quarters from Delaware, Georgia, Connecticut, and Arkansas and they all have some gold on the back. The pic I took is a bit blurry because i received them with a plastic cover that perfectly outlines the picture on the front and back and it's hard to keep aligned. I have found these type of quarters but it looks like people used them to make necklaces, cuff links, and money clips out of them. Does anyone know about these quarters and what they're worth? Thanks
