Mewtwo GX

A PSA 10 currently sells for about £6,394, raw the card sits at £564.77 — 11.3× as much. Of 17.802 copies already graded, 16 % received a 10 and 40 % a 9. Mathematically, submitting returns £1,944 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 281 auctions the median was £562.77, across 415 fixed-price sales £595.05. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between £303.21 and £579.04, with a median of £441.04. 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 £217.63. Offers well below £130.58 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 £540.27 (617), Italian £451.86 (19), French £337.00 (17). English fetches about 91 % more.

Last Sold 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.
