A PSA 10 currently sells for about £51.76, raw the card sits at £20.63 — 2,5× as much. Mathematically, submitting returns £51.76 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.

Across 123 auctions the median was £13.64, across 325 fixed-price sales £14.36. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between £10.45 and £14.97, with a median of £12.69. 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 £8.18. Offers well below £4.91 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 £22.39 (10), Japanese £12.77 (413). English fetches about 75 % 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.
