A PSA 10 currently sells for about £157.82, raw the card sits at £12.36 — 12,8× as much. Of 4.061 copies already graded, 44 % received a 10 and 46 % a 9. Mathematically, submitting returns £82.03 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 89 auctions the median was £12.43, across 344 fixed-price sales £13.83. Fixed price therefore fetched about 11 % more — for this card patience with a set price is the better route.

Half of all sales fell between £11.43 and £14.78, with a median of £12.81. 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 £10.05. Offers well below £6.03 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 £16.15 (46), Italian £12.40 (10), English £10.44 (499). German fetches about 55 % 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.
