A 1970 San Francisco Giants Team Signed Baseball with the key signatures: Mays, McCovey, Marichal, Perry, Bonds, and Foster is worth about $175.-$275. Value is based on average prices of recently closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the baseball. Prices may also vary based on the amount of signatures, and key signatures acquired. The more complete the baseball with key signatures the more valuable. If the signatures are not properly authenticated the baseball could sell at half the market value or less.

Autographed baseball cardsIn general, collectors of baseball cards would rather have a baseball card without the signature. The signature would be considered as a flaw in the condition of the card and will lower the value. If the signature has a lower value than the card it will lower the value of the card. The un-signed card will have a higher value.
