COA Guide tracks autograph-authenticator lookup pages

Editorial interest 77/100 Selection signal · not a rating of the site

A sourced directory of autograph certificate issuers, with lookup-status checks and guides to verification.

Landing page captured for the 2026-10-16 issue.

For: Autograph collectors checking a certificate issuer
Worth noticing: The status board distinguishes a responding page from a successful authenticity check, and labels blocked automated checks separately.

Field notes

The homepage organizes issuer lookup pages under a status board and separates offline pages from checks blocked by the issuer’s site. Its latest visible issue is Flags & Fakes #2, dated Oct. 15, 2026, and the offered newsletter covers outages, policy changes, and new research. The page cautions that a responding lookup page has only loaded for an automated check; that status does not confirm the accuracy of its results.
