Slowpoke & Psyduck GX

A PSA 10 currently sells for about €583,87, raw the card sits at €122,98 — 4,7× as much. Of 1.776 copies already graded, 37 % received a 10 and 46 % a 9. Mathematically, submitting returns €307,04 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 25 auctions the median was €108,21, across 85 fixed-price sales €119,04. Fixed price therefore fetched about 10 % more — for this card patience with a set price is the better route.

Half of all sales fell between €89,21 and €128,41, with a median of €108,07. 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 €62,18. Offers well below €37,31 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

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.
