A PSA 10 currently sells for about £324.47, raw the card sits at £11.12 — 29,2× as much. Of 2.956 copies already graded, 16 % received a 10 and 37 % a 9. Mathematically, submitting returns £103.06 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 29 auctions the median was £8.51, across 66 fixed-price sales £8.97. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between £4.39 and £14.12, with a median of £7.44. 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 £2.98. Offers well below £1.79 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: English £6.69 (70), French £5.76 (11). English fetches about 16 % 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.
