A PSA 10 currently sells for about £91.81, raw the card sits at £2.24 — 41,1× as much. Mathematically, submitting returns £91.81 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 14 auctions the median was £1.67, across 28 fixed-price sales £2.56. Fixed price therefore fetched about 54 % more — for this card patience with a set price is the better route.

Half of all sales fell between £1.58 and £2.98, with a median of £2.23. 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 £1.11. Offers well below £0.67 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.
