Mewtwo GX

A PSA 10 currently sells for about £102.35, raw the card sits at £6.51 — 15.7× as much. Of 7.859 copies already graded, 57 % received a 10 and 34 % a 9. Mathematically, submitting returns £70.72 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 113 auctions the median was £4.54, across 356 fixed-price sales £6.19. Fixed price therefore fetched about 36 % more — for this card patience with a set price is the better route.

Half of all sales fell between £4.29 and £6.94, with a median of £5.25. 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 £3.07. Offers well below £1.84 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: German £8.25 (26), English £6.65 (545), French £2.85 (24). German fetches about 190 % 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.
