I have a Nolan Ryan and Tom Seaver 1967 Rookie Pitchers baseball card. Ryan's card is on the left and Seaver's card is on the right. Both are in Mets uniforms and have their hands above their head. Both cards have their signatures. The card has a Mets logo on it. It is enclosed in a plastic covering. A Certificate of Authenticity "Nolan Ryan and Tom Seaver Rookie Card" is number 9942 of 10,000, signed by Steve Starr, Acme Reproductions. A "Official Licensee Major League Baseball" Logo is part of the certificate.
The card measures 4 1/4 inches by 3 1/8 inches. What is its Value?

Because it's signed and because it's not truly Ryan's rookie card, probably not worth much
