Give a piece of practical advice (big or small, general about buying or specfic to a card) that the collector who has been collecting a while can use. Not total beginner stuff ("Buy an SCD," "Topps was sold with gum"), but for readers of this board.
An example advice would be, "When in doubt, assume a card is not a proof. Most printing errors, blank backs and strange variations are scrapps or errors, and are not proofs."
