A graded card is sealed in a tamper-evident slab by an independent grader, PSA, CGC or BGS, with a numeric grade for centring, corners, edges and surface. Grading settles two questions at once: the card is authentic, and its condition is described by someone other than the seller. Every card here is listed with its grader and grade, and the slab itself carries the certification number you can check on the grader's own lookup. Slabs ship double-boxed with tracking anywhere in Thailand, or you can inspect them in person at the Patong store.
