Completed eBay sales of raw copies. Listings that read as graded, lots or non-English, prices far from the TCGplayer market, and prices that match this card's PSA 9s are left out.
Grading with PSA pays if your copy has better than a 40% chance of a 10.
36% of the 148 copies PSA has graded got a 10. People mostly send their cleanest copies, so a typical raw copy's odds are lower.
