A PSA 10 currently sells for about £2,657, raw the card sits at £343.98 — 7,7× as much. Of 25.930 copies already graded, 16 % received a 10 and 51 % a 9. Mathematically, submitting returns £729.37 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 468 auctions the median was £268.41, across 815 fixed-price sales £297.57. 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 £219.50 and £297.58, with a median of £261.40. 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 £167.91. Offers well below £100.75 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 £338.72 (32), English £283.48 (1049), German £153.02 (123). Italian fetches about 172 % 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.
