The Rip Test: Why Core Color Is Not an Authenticity Verdict

Tearing permanently damages the card and core color alone cannot authenticate it. Do not use the rip test, even as a last resort.

Caution: Not recommended for any authentication decision. Tearing is irreversible, including when the card turns out to be genuine.

What this checks

Only the exposed stock construction, not whether Wizards printed or assembled the card.

Compare your card against a verified genuine scan like this — look for a genuine card may have a blue or another documented core construction; do not tear it to find out. A counterfeit instead shows: a different core can prompt investigation, but matching a core color is not proof of authenticity either.

A different core can prompt investigation, but matching a core color is not proof of authenticity either.

Step by step

  1. 1Keep the card intact; do not tear, cut, or peel it.
  2. 2Inspect existing edges under magnification without applying stress.
  3. 3Compare both printed faces with the correct genuine version.
  4. 4Photograph concerns and ask an experienced examiner or the marketplace for next steps.

Why it matters

A destructive observation is not automatically conclusive. Preserve the card for expert examination and any dispute rather than sacrificing it to a stock-color rule.
