Frequently asked
How can I tell if my Mermaid Knight is real?
Mermaid Knight is not on our list of commonly-counterfeited cards, but counterfeits exist across every set. Check the holographic sticker on the bottom-right of the card face (real cards have a specific Konami anti-counterfeit pattern), the cardstock thickness and texture, font weight on the card name, and verify the set code printed on the card. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
