Mewtwo & Mew GX

A PSA 10 currently sells for about £1,526, raw the card sits at £274.16 — 5.6× as much. Of 3.113 copies already graded, 41 % received a 10 and 40 % a 9. Mathematically, submitting returns £830.67 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 39 auctions the median was £260.99, across 68 fixed-price sales £282.79. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between £117.08 and £279.65, with a median of £207.31. 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 £84.88. Offers well below £50.93 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.
