A PSA 10 currently sells for about $667.64, raw the card sits at $85.89 — 7,8× as much. Of 496 copies already graded, 38 % received a 10 and 38 % a 9. Mathematically, submitting returns $372.83 on average, before fees and shipping. Rule of thumb: submit when the value at a realistic grade is at least double the raw value — which is the case here. Centering decides it: an off-centre card will not get a 10. The grade distribution comes from the PSA Population Report; people pre-sort before submitting, so your own hit rate may differ.

Across 20 auctions the median was $54.28, across 44 fixed-price sales $71.39. Fixed price therefore fetched about 32 % more — for this card patience with a set price is the better route.

Half of all sales fell between $42.24 and $71.39, with a median of $58.39. Selling fast lands you nearer the lower end; with patience, good photos and a complete title the upper end is achievable.

The cheapest genuine sales were around $25.26. Offers well below $15.15 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

lastsold uses only real sales — eBay plus auction houses like Goldin & Fanatics — recent sales count more (recency weighting), outliers and fakes are removed. It's not an estimate but actual sold prices, separated by condition, language and grading.
