A PSA 10 currently sells for about £506.16, raw the card sits at £69.98 — 7,2× as much. Of 1.410 copies already graded, 23 % received a 10 and 38 % a 9. Mathematically, submitting returns £216.35 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 51 auctions the median was £38.71, across 154 fixed-price sales £44.37. Fixed price therefore fetched about 15 % more — for this card patience with a set price is the better route.

Half of all sales fell between £32.70 and £47.82, with a median of £39.79. 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 £25.44. Offers well below £15.27 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 £44.67 (252), Japanese £34.45 (13). English fetches about 30 % 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.
