A PSA 10 currently sells for about £555.55, raw the card sits at £172.75 — 3,2× as much. Of 2.339 copies already graded, 47 % received a 10 and 35 % a 9. Mathematically, submitting returns £357.20 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 40 auctions the median was £143.33, across 90 fixed-price sales £127.55. Auctions therefore fetched about 12 % more — worth it mainly for sought-after cards with several bidders.

Half of all sales fell between £93.54 and £149.66, with a median of £119.90. 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 £69.45. Offers well below £41.67 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.
