A PSA 10 currently sells for about £1,620, raw the card sits at £149.16 — 10,9× as much. Of 602 copies already graded, 18 % received a 10 and 34 % a 9. Mathematically, submitting returns £749.82 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 129 auctions the median was £107.75, across 264 fixed-price sales £130.26. 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 £81.92 and £146.06, with a median of £113.52. 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 £60.00. Offers well below £36.00 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: German £109.85 (26), English £97.70 (429), French £52.87 (10). German fetches about 108 % 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.
