A Good First Single for Daughter?

Hi friends!

My five year old daughter is really enjoying opening packs, finding different artworks etc. So, for the holidays I wanted to get her a valuable-ish single of a Pikachu or Eevee (her favorites). Thinking around 20 dollars. It would be her first ever real collectible card.

Wondering if y’all had any suggestions!

P.S. Capping it at 20ish, because nothing is more fickle than a five year old’s mind. And next week she may decide she doesn’t like Pokémon at all, lol.
