The price at £200.04 hasn't budged in 40 days while the set has dropped 12.6% over a month, which is a warning sign. Only one UK seller has it, asking £210—a thin market where you'll need to price carefully and accept a slow sale. Raw copies have actually shifted for £199 across 26 sales in the last 90 days, so that single ask at £210 is sitting above what collectors are paying. The ask itself has come down 8.7% from £230, but don't be tempted by the PSA 10 route at £635.45; those haven't sold in a fortnight and grading costs don't stack up here.
