Grass Energy

The 2017 Guardians Rising Grass Energy is a secret rare Energy card. Raw near-mint copies trade around $22.25, while a PSA 10 is modelled near $67.25 and a PSA 9 near $40.25. In its original set it is a chase card — roughly a 1-in-2,000 booster pull (modelled, not official). Grass Energy has 12 other printings in the catalogue.
