A PSA 10 currently sells for about £1,233, raw the card sits at £139.62 — 8,8× as much. Of 537 copies already graded, 31 % received a 10 and 35 % a 9. Mathematically, submitting returns £628.07 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 34 auctions the median was £119.09, across 70 fixed-price sales £104.84. Auctions therefore fetched about 14 % more — worth it mainly for sought-after cards with several bidders.

Half of all sales fell between £63.77 and £134.75, with a median of £93.62. 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 £42.52. Offers well below £25.51 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 £109.61 (84), German £55.82 (11). English fetches about 96 % 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.
