Frequently asked

How can I tell if my Zweilous is real?

Zweilous is not on our list of commonly-counterfeited cards, but counterfeits exist across every set. Check the back-light test (real cards have a black inner layer that blocks light; counterfeits glow through), the rosette dot pattern on the back under magnification, font weight and kerning on the card name, and the holofoil pattern if applicable. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
