Slowpoke & Psyduck GX

A PSA 10 currently sells for about $788.05, raw the card sits at $141.48 — 5,6× as much. Of 4.121 copies already graded, 38 % received a 10 and 42 % a 9. Mathematically, submitting returns $424.17 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 124 auctions the median was $98.04, across 342 fixed-price sales $111.14. Fixed price therefore fetched about 13 % more — for this card patience with a set price is the better route.

Half of all sales fell between $76.43 and $119.74, with a median of $97.69. 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 $57.09. Offers well below $34.25 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: Italian $119.77 (17), English $99.70 (447), German $74.49 (16). Italian fetches about 61 % 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.
