A PSA 10 currently sells for about £7,931, raw the card sits at £112.66 — 70,4× as much. Of 2.997 copies already graded, 4 % received a 10 and 26 % a 9. Mathematically, submitting returns £857.41 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 93 auctions the median was £68.95, across 61 fixed-price sales £84.95. Fixed price therefore fetched about 23 % more — for this card patience with a set price is the better route.

Half of all sales fell between £20.83 and £59.71, with a median of £39.80. 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 £11.05. Offers well below £6.63 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 £62.90 (19), French £45.10 (22). English fetches about 39 % 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.
