Slowpoke & Psyduck GX

A PSA 10 currently sells for about £1,939, raw the card sits at £279.46 — 6.9× as much. Of 3.804 copies already graded, 41 % received a 10 and 42 % a 9. Mathematically, submitting returns £1,034 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 84 auctions the median was £245.54, across 197 fixed-price sales £245.84. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between £118.83 and £239.84, with a median of £197.82. 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 £67.90. Offers well below £40.74 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 £270.83 (236), German £133.45 (12). English fetches about 103 % 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.
