A PSA 10 currently sells for about £151.70, raw the card sits at £8.75 — 17,3× as much. Of 234 copies already graded, 38 % received a 10 and 32 % a 9. Mathematically, submitting returns £96.99 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 15 auctions the median was £10.69, across 55 fixed-price sales £10.33. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between £7.23 and £14.71, with a median of £10.34. 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 £4.24. Offers well below £2.55 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.
