Slowpoke & Psyduck GX

A PSA 10 currently sells for about $2,560, raw the card sits at $557.94 — 4.6× as much. Of 3.847 copies already graded, 41 % received a 10 and 43 % a 9. Mathematically, submitting returns $1,368 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 85 auctions the median was $315.49, across 200 fixed-price sales $327.37. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between $158.93 and $322.72, with a median of $261.51. 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 $89.70. Offers well below $53.82 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 $397.39 (237), German $208.30 (13). English fetches about 91 % 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.
