A PSA 10 currently sells for about £299.44, raw the card sits at £25.84 — 11,6× as much. Of 2.904 copies already graded, 27 % received a 10 and 51 % a 9. Mathematically, submitting returns £119.56 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 138 auctions the median was £21.52, across 328 fixed-price sales £26.10. Fixed price therefore fetched about 21 % more — for this card patience with a set price is the better route.

Half of all sales fell between £19.60 and £28.74, with a median of £23.66. 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 £15.54. Offers well below £9.33 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

From real sales: English £24.43 (571), German £21.26 (38). English fetches about 15 % more.

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.
