A PSA 10 currently sells for about £369.16, raw the card sits at £15.00 — 24,6× as much. Of 236 copies already graded, 28 % received a 10 and 29 % a 9. Mathematically, submitting returns £173.50 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 101 auctions the median was £11.48, across 328 fixed-price sales £14.59. Fixed price therefore fetched about 27 % more — for this card patience with a set price is the better route.

Half of all sales fell between £10.36 and £16.82, with a median of £13.57. 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 £7.67. Offers well below £4.60 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 £25.50 (34), English £14.91 (590), French £12.75 (11). German fetches about 100 % 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.
