What is restoration?
• Restoration is treatment intended to return a comic book to a known or assumed state for aesthetic enhancement by adding non-original material. Detected restoration is always disclosed on the CGC certification label. Non-additive procedures, such as pressing, dry cleaning and tape removal are not classified as restoration by CGC. Trimmed books are given an apparent grade, and, in accordance with CGC’s policy, encapsulated with CGC’s restored label. Learn more about comic book restoration.
