Arceus & Dialga & Palkia GX

The cheapest copy at £32.99 has been sitting unsold for 7 days, so undercut it if you want to move stock. This card is sliding hard—down 15.1% this week and 44.7% this month—so list now or sit tight and wait for a floor. The damaged flag on that £32.99 listing means a clean played copy can command more, and a Near Mint example is genuinely rare among the five UK listings. Raw copies actually sell for a £49.38 median across 28 sales over 90 days with about 2.5 moving per week, so don't be spooked by the low ask; grading to PSA 10 isn't worth the risk unless the copy is flawless, given the gap of 6.4× between a 10 (£422.73) and a 9 (£66.54).
