ed States Coins is a convenient way for collectors to keep track of their U.S. coin collections. Each volume packs a lot of information into one handy resource you can carry in your pocket or bag. Take it to coin shows and shops while you're on the hunt for your next purchase. The spiral binding allows you to easily flip it open for note-taking. Inside is plenty of room to write down when and where you bought each coin, its grade, the price you paid, who sold it, or other information you want to record.
