Blastoise

A PSA 10 currently sells for about £5,541, raw the card sits at £330.88 — 16,7× as much. Of 505 copies already graded, 8 % received a 10 and 21 % a 9. Mathematically, submitting returns £1,028 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 83 auctions the median was £15.31, across 168 fixed-price sales £12.53. Auctions therefore fetched about 22 % more — worth it mainly for sought-after cards with several bidders.

Half of all sales fell between £6.63 and £15.95, with a median of £10.01. 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 £3.77. Offers well below £2.26 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 £15.13 (318), German £7.62 (23). English fetches about 99 % 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.
