Grading Theinen the Great Sphinx #EP1-EN001 pays only if you expect a 10: PSA 10 copies sell for about $168.89 and grade 8 copies for $19.99 (PriceCharting sold listings, Nov 2, 2026) vs $0.60 raw (TCGplayer market), and after a $25 grading fee, $10 shipping and 13% selling fees you'd need about 1 in 7 copies to grade a 10 to break even (a 14% chance). That assumes a copy that misses the 10 sells as a grade 8. Whether your copy grades a 10 depends on its centering, corners, edges and surface. Prices from PriceCharting (pricecharting.com).
