A PSA 10 currently sells for about £141.04, raw the card sits at £1.57 — 89,7× as much. Of 37.506 copies already graded, 56 % received a 10 and 38 % a 9. Mathematically, submitting returns £87.83 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 7 auctions the median was £0.55, across 10 fixed-price sales £1.33. Fixed price therefore fetched about 140 % more — for this card patience with a set price is the better route.

Half of all sales fell between £0.99 and £1.98, with a median of £1.55. 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 £0.78. Offers well below £0.47 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: German £2.87 (10), English £1.56 (73). German fetches about 84 % 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.
