Koffing card value

Koffing cards span the years 1999 to 2025, and the most valuable Koffing card is the Secret Rare from Cosmic Eclipse in 2019. All 29 of the 29 Koffing cards carry a market value, and the ten leading cards hold 91 percent of the total, so the top of the list sets the Koffing card value for the whole species, with the rest of the cards sharing only a small slice.

What makes the top Koffing cards valuable

The Cosmic Eclipse Secret Rare from 2019 leads the most valuable Koffing cards by 4.3 times over the next card, the Shiny rare from the Shining Fates Shiny Vault in 2021. Third is the Common from Expedition Base Set, printed in 2002. Fourth and fifth are Commons from Delta Species and Deoxys, both from 2005. Koga's Koffing from Gym Challenge, an Uncommon from 2000, sits 6th.

Koffing cards by era

Koffing cards in the top twenty-five come from nine eras. The WOTC era supplies five of them and the EX era four, while Sun & Moon and Sword & Shield give three each. The newest leader is the Journey Together Koffing from 2025, which sits 24th overall. Vintage, meaning the WOTC era, holds four of the top ten and five of the top twenty-five, while modern cards make up six of the top ten and twenty of the top twenty-five.

Rarities and prints among the top Koffing cards

Among the ten leading Koffing cards, seven are Commons, with one Secret Rare, one Shiny rare and one Uncommon. Widening to the leading twenty-five, the count is twenty Commons, three Uncommons, one Secret Rare and one Shiny rare. No Holo Rare, 1st Edition or Shadowless print appears in the ten leaders. Koffing cards of this value are overwhelmingly Commons, led by one Secret Rare.

How Koffing cards compare with other Pokémon

Ranked by the value of its single leading card, Koffing places 375th of 1020 species with priced cards. By the combined value of its ten leaders it places 396th of 753. Weezing, the only other member of the evolution line, ranks 284th of 1020 by its top card, ahead of Koffing. The Koffing card market sits in the middle of the field, built on one Secret Rare and a long run of Commons.
