Muk

Muk sits at #28 in Fossil, the third of the Wizards of the Coast print runs. Illustration by Mitsuhiro Arita. Arita was the original Pokémon TCG illustrator and the artist behind the Base Set Charizard. His vintage-era art has a painterly quality that distinguishes it from the cleaner reference-style work of the Sugimori cards. In the games, Muk evolves from Grimer, which makes it a late-stage card in the line.

The flavor text on the card reads: "Thickly covered with a filthy, vile sludge. It is so toxic, even its footprints contain poison." Pokédex entries from this era are short and often quirky, written by the original Japanese localization team for a specific stat-block layout that no longer exists in modern cards.

The fully evolved Grimer. Larger sludge mound. Fossil holo Muk is a quietly underrated card. Its Pokémon Power 'Toxic Gas' was a tournament-defining mechanic in 1999, which means surviving high-grade copies are scarcer than the print run suggests.

Fossil shipped in two print waves: 1st Edition (stamped) and Unlimited. There is no Shadowless equivalent for this set, and no widely-recognized error print on the scale of Jungle's No Symbol issue. Variant identification on Fossil is simpler than Base Set, but PSA 10 1st Edition populations are noticeably lower than the Base Set equivalents.

For graded buyers, non-holo Rares are less punishing on surface but no easier on centering. PSA 10 populations for Wizards-era Rares are smaller than the Rare Holo populations in some cases because the cards were less protected and more frequently played. Edge whitening from sleeves is the typical grade-cap on raw copies.

For raw purchases of this card, verify centering by eye, edge whitening on all four sides, and surface scratches under angled light. Non-holo Rares from the Wizards era are cheap enough that PSA 10 submissions usually do not break the math if you have a clean candidate.
