About ErrorCoins.co

ErrorCoins.co exists to reduce false error claims by teaching production mechanics, evidence recording, damage controls, and honest marketplace comparison.

We separate one-off mint errors, repeatable die varieties, and post-mint damage. The site is educational and does not provide formal authentication or appraisal. Our commercial links are focused research paths, not endorsements of seller descriptions.
