"Book value" and price-guide numbers are estimates or asking prices, not what buyers are actually paying. Real value is set by recent sold prices for the same card in the same condition — and those are often lower than list prices, especially once fees are considered. Condition also matters enormously: a guide may quote a Mint price while your copy is played. And shops or dealers pay a percentage of resale, not full retail, because they need margin. To gauge a realistic number, look at completed/sold sales for your exact card and grade. If you're selling to a shop, expect an offer below those comps in exchange for instant, fee-free cash.
