A PSA 10 currently sells for about £190.70, raw the card sits at £13.59 — 14,0× as much. Of 191 copies already graded, 35 % received a 10 and 39 % a 9. Mathematically, submitting returns £839.93 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 12 auctions the median was £5.05, across 54 fixed-price sales £8.52. Fixed price therefore fetched about 69 % more — for this card patience with a set price is the better route.

Half of all sales fell between £4.45 and £13.29, with a median of £7.11. 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 £3.31. Offers well below £1.98 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.
