Muk is card #28/62 in the 1999 Pokemon Fossil set (Rare), the third English Pokemon TCG expansion (Wizards of the Coast, October 1999). It was printed in 1st Edition and Unlimited, plus the scarce Australian 1999-2000 print. PSA has graded about 1,830 copies across its printings.
Print variants & how to tell them apart
1st Edition
The 'Edition 1' stamp — a black circle containing the number 1 — sits just left of the artwork, below the art box. The artwork and drop shadow are identical to Unlimited; the stamp is the only difference. The first, scarcest and most valuable English printing.
Unlimited
No 'Edition 1' stamp. Identical artwork and drop shadow to the 1st Edition card. By far the most common printing. Fossil never had a Shadowless print, so there is no copyright-line tell — only the missing stamp separates Unlimited from 1st Edition.
Shown: the Unlimited scan -- the Australian 1999-2000 print is identical except the (c)1999-2000 date and glossier stock. A true scan is coming.

PSA & SGC graded population by printing & grade. Half grades fold down for both graders (8.5→8); PSA qualified slabs (OC, ST, PD, MC and the like) are not counted. PSA Unlimited includes copies graded before PSA flagged the 1st Edition variety; SGC does not separate the 1999-2000 print.

Pokémon Power: Toxic Gas
Ignore all Pokémon Powers other than Toxic Gases. This power stops working while Muk is Asleep, Confused, or Paralyzed.
Thickly covered with a filthy, vile sludge. It is so toxic, even its footprints contain poison.
Market values are live TCGplayer prices for each printing. A dash means TCGplayer has no separate or active listing for that variant (e.g. 1999-2000). As an eBay Partner & affiliate we may earn from qualifying purchases.
Fossil cards come in two English printings: 1st Edition (with the Edition-1 stamp left of the art) and Unlimited (no stamp). Unlike Base Set there is no Shadowless print -- the art and drop shadow are identical, so the stamp is the only tell. The 47 non-holo cards also exist in a scarce Australian 1999-2000 'Red Logo' print (the copyright reads (c)1999-2000 and the stock is glossier).
