A PSA 10 currently sells for about £526.52, raw the card sits at £28.33 — 18,6× as much. Of 7.606 copies already graded, 13 % received a 10 and 53 % a 9. Mathematically, submitting returns £108.96 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 307 auctions the median was £27.27, across 607 fixed-price sales £30.81. Fixed price therefore fetched about 13 % more — for this card patience with a set price is the better route.

Half of all sales fell between £25.49 and £34.00, with a median of £29.34. 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 £20.29. Offers well below £12.17 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 £28.38 (815), French £27.08 (22), German £15.14 (86). English fetches about 144 % 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.
