rare and expensive pokemon cards The 10 Most Pokémon of 2022 (So Far) The 11 Most Expensive Pokémon
Description
The Charizard, Pokmon (1999) Base Set 1st Edition Holo graded CGC Gem Mint 10 (on the updated CGC Cards Grading Scale) realized $87,500, which is the highest price realized for a CGC-certified English Base Set 1st Edition Holo Charizard card on Heritage Auctions platform

When a card from that era surfaces in pristine condition, it demands premium prices

This is because the BGS Black Label is seen as an ultimate pristine card, and some collectors will pay a huge premium for that perfect label
