Averaged over those odds: ≈ $2,171.97 per slab, before selling fees.
Best case: the return if this card grades PSA 10, net of the $80.00 fee and a ~8-week turnaround haircut, before selling fees. 16% of copies submitted to PSA came back a 10, but submitted copies are hand-picked. Break-even is the chance of a 10 your copy needs for grading to pay on average.

Market

Supply & demand

How many copies are for sale, and how fast they're selling.
Raw
Sold / week—
Supply shows both venues: eBay active listings + TCGplayer sellers (distinct units, not summed); the supply-trend gauge is eBay-driven for now, with the TCGplayer trend surfacing once its history is reliable, then blending. Sold/wk is TCGplayer; demand pressure = weekly TCGplayer sales ÷ eBay active listings (soft → hot) — a relative read, not a literal sell-through. Descriptive market context, not a forecast.
