A PSA 10 currently sells for about £579.01, raw the card sits at £63.30 — 9.1× as much. Of 6.888 copies already graded, 31 % received a 10 and 42 % a 9. Mathematically, submitting returns £252.41 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 172 auctions the median was £48.55, across 402 fixed-price sales £63.01. 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 £47.22 and £69.22, with a median of £58.42. 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 £36.53. Offers well below £21.92 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: Italian £72.01 (26), French £71.25 (11), English £59.47 (572). Italian fetches about 56 % 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.
