A PSA 10 currently sells for about £47.73, raw the card sits at £4.37 — 10.9× as much. Of 2.505 copies already graded, 31 % received a 10 and 55 % a 9. Mathematically, submitting returns £23.93 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 207 auctions the median was £2.60, across 654 fixed-price sales £3.55. Fixed price therefore fetched about 37 % more — for this card patience with a set price is the better route.

Half of all sales fell between £2.76 and £4.09, with a median of £3.34. 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 £2.17. Offers well below £1.30 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: French £5.63 (23), Italian £3.84 (50), English £3.14 (922). French fetches about 122 % more.

Last Sold 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.
