Riolu #81 — Pokémon Stellar Crown Card Value

Which version do you have?

For the cheapest way to own Riolu #81, purchase the Standard version for $0. The Reverse Holo version at $1 offers slightly more collectibility, though the difference here is minimal in terms of edition or scarcity. If your goal is simply to have the card, stick to the Standard. If you want a slightly more desirable version, the $1 Reverse Holo is the better, low-cost upgrade.
