A PSA 10 currently sells for about £531.37, raw the card sits at £39.54 — 13.4× as much. Of 6.932 copies already graded, 31 % received a 10 and 42 % a 9. Mathematically, submitting returns £238.86 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 195 auctions the median was £50.28, across 448 fixed-price sales £63.22. Fixed price therefore fetched about 26 % more — for this card patience with a set price is the better route.

Half of all sales fell between £47.59 and £69.05, with a median of £58.47. 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 £36.85. Offers well below £22.11 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 £72.12 (24), French £69.76 (11), English £60.45 (622). Italian 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.
