book value is for retards, cash value is the most important factor in the hobby. people who go by book value are the ones with items that dont sell well, but still carry a high book value because beckett hasnt bothered or noticed to adjust the price on older guys (say byron leftwich for example). he might book 100 on a given card and sell for $10, while jay cutler might book 100 and sell for 55, is trading the cutler for leftwich a wise idea? no
