Blastoise

A PSA 10 currently sells for about £410.30, raw the card sits at £9.03 — 45,4× as much. Of 352 copies already graded, 23 % received a 10 and 43 % a 9. Mathematically, submitting returns £137.78 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 16 auctions the median was £5.11, across 91 fixed-price sales £6.32. Fixed price therefore fetched about 24 % more — for this card patience with a set price is the better route.

Half of all sales fell between £4.74 and £8.00, with a median of £5.99. 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 £3.49. Offers well below £2.09 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: German £8.19 (10), English £7.46 (213). German fetches about 10 % 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.
