Qualified

"Qualified" grades are used by CGC for collectibles that denote that a signed book was autographed outside of an official CGC signing. Many modern comicbooks are available to be signed by the writers and artists when ordered directly from the publishing company, so this is not entirely uncommon. Golden and Silver Age comics that are considered very rare are difficult to have authenticated since the original artists may be deceased, which also means a "Signature Series" grade is not very common.
