Siebold

The 2021 Chilling Reign Siebold is an ultra rare Trainer card, illustrated by Hideki Ishikawa. Raw near-mint copies trade around $3.04, while a PSA 10 is modelled near $48.04 and a PSA 9 near $21.04. In its original set it is a chase card — roughly a 1-in-650 booster pull (modelled, not official). Siebold has 2 other printings in the catalogue.
