  • Required for any complete Onix master set across eras.
  • Collectors of the Base Set set need this card to finish it.

10Grading and Population

PSA 10 estimate: WotC-era Onix PSA 10 populations vary; small numbers across most sets.

Graded copies command notable premiums over raw, especially for 1st Edition prints.

Other graders: BGS and CGC also grade vintage Pokemon; PSA dominates secondary-market liquidity.
