Which version do you have?

If you just want Mamoswine #21, grab the Standard version for $0. The Reverse Holo version at $1 offers a slight aesthetic upgrade, but the difference in collectibility is minimal given the low prices. For a casual owner, the Standard version is perfectly fine. Only pay the extra dollar for the Reverse Holo if you specifically want that holo pattern, otherwise, save your money.
