Greninja GX

A PSA 10 currently sells for about £216.23, raw the card sits at £13.59 — 15.9× as much. Of 440 copies already graded, 47 % received a 10 and 36 % a 9. Mathematically, submitting returns £132.00 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 31 auctions the median was £11.26, across 131 fixed-price sales £13.19. Fixed price therefore fetched about 17 % more — for this card patience with a set price is the better route.

Half of all sales fell between £10.37 and £14.89, with a median of £12.67. 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 £7.33. Offers well below £4.40 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 £14.35 (189), German £9.70 (11). English fetches about 48 % 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.
