A PSA 10 currently sells for about £578.45, raw the card sits at £63.42 — 9,1× as much. Of 6.586 copies already graded, 31 % received a 10 and 42 % a 9. Mathematically, submitting returns £249.98 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 171 auctions the median was £48.56, across 423 fixed-price sales £63.00. Fixed price therefore fetched about 30 % more — for this card patience with a set price is the better route.

Half of all sales fell between £47.44 and £68.72, with a median of £58.44. 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 £36.67. Offers well below £22.00 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: French £72.77 (12), Italian £72.42 (20), English £59.43 (591). French fetches about 57 % 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.
