Wartortle

A PSA 10 currently sells for about £189.29, raw the card sits at £3.97 — 47,7× as much. Of 2.344 copies already graded, 13 % received a 10 and 20 % a 9. Mathematically, submitting returns £70.08 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 131 auctions the median was £4.41, across 277 fixed-price sales £3.72. Auctions therefore fetched about 19 % more — worth it mainly for sought-after cards with several bidders.

Half of all sales fell between £1.99 and £4.42, with a median of £2.99. 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 £1.28. Offers well below £0.77 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 £3.77 (242), German £3.61 (92), Italian £2.85 (11). English fetches about 32 % 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.
