Another major factor driving raw singles off TCGplayer is the grading arbitrage window. Professional grading registries show that modern One Piece cards generally boast high production quality, yet centering imperfections and edge-chipping on dark-bordered foil cards still sink gem mint odds. A verified PSA 10 graded Sabo commands a 100% to 150% premium over raw near-mint pricing.
Speculative grading outfits routinely buy near-mint copies at $900 with the explicit strategy of fast-track grading through PSA or BGS. If the card returns a Gem Mint 10, immediate realized profits comfortably offset grading fees and platform commissions. This structural arbitrage sets an artificial floor beneath raw singles. As long as graded sales clear at $2,500, buyers will treat raw copies under $1,000 as discounted entry points.
