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.
The age of when the ball was signed does not determine the value. Supply and demand does. The value of the signature will rely on the popularity of the player that signed the ball, and how often he signed. If there are more collectors than signatures on the market the value will be high. If there are many signatures on the market and a lower number of collectors, a lower value.
If the baseball is "multi-signed", and not "single signed" you would have to name the other players that signed the baseball to get an approximate value.
