Arceus & Dialga & Palkia GX

A PSA 10 currently sells for about £367.38, raw the card sits at £53.03 — 6.9× as much. Of 1.410 copies already graded, 43 % received a 10 and 39 % a 9. Mathematically, submitting returns £218.31 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 31 auctions the median was £35.51, across 78 fixed-price sales £46.61. 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 £31.58 and £47.28, with a median of £38.93. 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 £21.92. Offers well below £13.15 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

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.
