What is the value of a 1974 Pittsburgh Pirates Team Signed Baseball?

Answer 1

A 1974 Pittsburgh Pirates Team Signed Baseball with the key signatures: Stargell, Oliver, Parker, and Tekulve is worth about $150.-$200. 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.
