A PSA 10 currently sells for about £362.36, raw the card sits at £2.93 — 123,5× as much. Of 229 copies already graded, 13 % received a 10 and 28 % a 9. Mathematically, submitting returns £146.43 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 £4.25, across 90 fixed-price sales £3.55. Auctions therefore fetched about 20 % more — worth it mainly for sought-after cards with several bidders.

Half of all sales fell between £2.21 and £4.44, with a median of £2.85. 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 £1.45. Offers well below £0.87 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.
