Cleffa

The cheapest copy listed at £11.33 is flagged as LP-graded, so a clean example should command more. The market here is dominated by played copies — 10 of the 12 known UK listings are played — which means Near Mint stock is genuinely scarce. Asking prices range from £11.33 to £18.67 median, with that cheapest sitting 39% under the middle, so there's room between the floor and what most sellers want. It's the 5th most valuable card in HGSS Black Star Promos, which explains the spread.
