Grading Slowpoke & Psyduck GX #239/236 pays only if you expect a 10: PSA 10 copies are listed from $975.99 on eBay (eBay asks checked Oct 24, 2026) vs $246.82 raw (TCGplayer market), and after a $25 grading fee, $10 shipping and 13% selling fees you'd need about 1 in 18 copies to grade a 10 to break even (a 6% chance). That assumes a 9 or lower sells like a raw copy. "Listed from" is the lowest current PSA 10 asking price on eBay, not a sale, and asks can sit above what copies actually sell for. Whether your copy grades a 10 depends on its centering, corners, edges and surface.
