Grading Thunder Mountain Prism Star #191/214 pays only if you expect a 10: PSA 10 copies sell for about $60.00 and grade 8 copies for $3.60 (PriceCharting sold listings, Nov 2, 2026) vs $1.52 raw (TCGplayer market), and after a $25 grading fee, $10 shipping and 13% selling fees you'd need about 1 in 1 copies to grade a 10 to break even (a 68% 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).
