Charizard cards have long since been some of the rarest and most expensive cards to add to a Pokémon fan's collection. The 1st Edition Charizard from the Base Set of Pokémon TCG is often described as the crown jewel of Pokémon itself. Charizard cards' rarity and expense haven't changed and cards in newer sets like the Sword & Shield series skyrocket above $100, even upon their initial release.
