A PSA 10 currently sells for about £37,099, raw the card sits at £2,598 — 14.3× as much. Mathematically, submitting returns £37,099 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.

Across 91 auctions the median was £251.01, across 89 fixed-price sales £370.22. Fixed price therefore fetched about 47 % more — for this card patience with a set price is the better route.

Half of all sales fell between £127.57 and £267.84, with a median of £184.43. 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 £74.43. Offers well below £44.66 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

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.
