Only One Graded

Set Description
This set contains comics that are the only graded example in current CGC population.

Set Goals
Get as many rare comics graded as possible. Since some low populations are just due to relative popularity of the book, issues past the Silver Age will not be considered for this set. As soon as another copy is graded, in any condition, the book will be removed from this set. This will be as up to date as possible.
