The cheapest copy listed at £3.31 is graded LP, so don't expect a clean example at that price — Near Mint copies are scarce since 64% of UK listings are played. The card's bounced between £4.98 and £6.00 over the last month, and asking prices span £3.31 to £5.89, with the cheapest sitting 44% below the median. If you're after foil instead, expect to pay 2.2× more at around £11.16.
