Blastoise GX

A PSA 10 currently sells for about £130.91, raw the card sits at £13.50 — 9.7× as much. Of 1.708 copies already graded, 51 % received a 10 and 35 % a 9. Mathematically, submitting returns £82.13 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 88 auctions the median was £9.37, across 215 fixed-price sales £13.53. Fixed price therefore fetched about 44 % more — for this card patience with a set price is the better route.

Half of all sales fell between £8.45 and £13.85, with a median of £11.04. 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 £5.65. Offers well below £3.39 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 £10.95 (283), German £7.77 (14). English fetches about 41 % 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.
