Blastoise & Piplup GX

A PSA 10 currently sells for about £633.96, raw the card sits at £62.02 — 10.2× as much. Of 5.991 copies already graded, 30 % received a 10 and 43 % a 9. Mathematically, submitting returns £267.47 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 236 auctions the median was £49.49, across 422 fixed-price sales £52.93. There is no meaningful difference — what matters here is how fast you want to sell.

Half of all sales fell between £38.07 and £58.86, with a median of £47.85. 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 £28.99. Offers well below £17.39 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: Italian £54.06 (11), English £52.50 (638), German £39.40 (24). Italian fetches about 37 % more.

Last Sold 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.
