A PSA 10 currently sells for about £239.52, raw the card sits at £19.74 — 12,1× as much. Of 166 copies already graded, 37 % received a 10 and 31 % a 9. Mathematically, submitting returns £151.69 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 10 auctions the median was £10.25, across 69 fixed-price sales £15.83. Fixed price therefore fetched about 54 % more — for this card patience with a set price is the better route.

Half of all sales fell between £14.18 and £19.57, with a median of £15.99. 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 £9.45. Offers well below £5.67 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.
