A PSA 10 currently sells for about £251.79, raw the card sits at £8.42 — 29.9× as much. Of 2.267 copies already graded, 19 % received a 10 and 54 % a 9. Mathematically, submitting returns £66.99 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 196 auctions the median was £8.52, across 708 fixed-price sales £9.40. Fixed price therefore fetched about 10 % more — for this card patience with a set price is the better route.

Half of all sales fell between £7.58 and £10.77, with a median of £9.07. 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 £6.47. Offers well below £3.88 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 £13.86 (16), German £10.69 (57), Italian £10.11 (21). French fetches about 62 % 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.
