Both certificates are signed but I can't make out the signature. If it becomes important I can scan it in and send it to you. The word "original" in red appears after the signature. Both certificates also say at the bottom: (copyright sign) 1980 Ruger Collectors' Association, Inc. P.O. Box 290, Southport, CT 06525.
