Grading Mewtwo GX #78/73 pays only if you expect a 10: PSA 10 copies list from $1,084 on eBay vs $813 raw, and after a $25 grading fee, $10 shipping and 13% selling fees you need about a 15% chance of a 10 to break even. That assumes a 9 or lower sells like a raw copy. "List from" is the lowest current PSA 10 asking price on eBay, not a sale; whether your copy grades a 10 depends on its condition, which TickerMint's verdict weighs for members.
