Umbreon & Darkrai GX

A PSA 10 currently sells for about £416.86, raw the card sits at £102.56 — 4,1× as much. Of 6.478 copies already graded, 44 % received a 10 and 38 % a 9. Mathematically, submitting returns £241.06 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 118 auctions the median was £53.94, across 343 fixed-price sales £71.00. Fixed price therefore fetched about 32 % more — for this card patience with a set price is the better route.

Half of all sales fell between £43.81 and £69.61, with a median of £54.87. 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 £31.54. Offers well below £18.92 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 £67.17 (413), French £38.11 (11), German £36.09 (30). English fetches about 86 % 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.
