Slowpoke & Psyduck GX

A PSA 10 currently sells for about $805.76, raw the card sits at $165.29 — 4.9× as much. Of 4.577 copies already graded, 38 % received a 10 and 42 % a 9. Mathematically, submitting returns $429.81 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 130 auctions the median was $98.09, across 351 fixed-price sales $111.53. Fixed price therefore fetched about 14 % more — for this card patience with a set price is the better route.

Half of all sales fell between $77.13 and $121.57, with a median of $98.24. 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 $57.32. Offers well below $34.39 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 $125.05 (465), Italian $124.03 (16), German $67.24 (16). English fetches about 86 % 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.
