Blastoise GX

A PSA 10 currently sells for about £112.53, raw the card sits at £12.44 — 9,0× as much. Of 2.051 copies already graded, 47 % received a 10 and 36 % a 9. Mathematically, submitting returns £69.72 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 61 auctions the median was £9.16, across 143 fixed-price sales £13.28. Fixed price therefore fetched about 45 % more — for this card patience with a set price is the better route.

Half of all sales fell between £8.84 and £13.82, with a median of £11.21. 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 £6.32. Offers well below £3.79 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 £10.47 (223), German £8.50 (12). English fetches about 23 % 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.
