Arceus & Dialga & Palkia GX

A PSA 10 currently sells for about £2,931, raw the card sits at £432.03 — 6.8× as much. Of 4.858 copies already graded, 35 % received a 10 and 41 % a 9. Mathematically, submitting returns £1,519 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 58 auctions the median was £299.13, across 145 fixed-price sales £392.66. Fixed price therefore fetched about 31 % more — for this card patience with a set price is the better route.

Half of all sales fell between £251.62 and £433.33, with a median of £336.20. 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 £165.36. Offers well below £99.21 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 £391.45 (211), Italian £334.32 (15). English fetches about 17 % 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.
