What is the value of a non-authenticated baseball autographed by the 1958 Detroit Tigers?

Answer 1

A 1958 Detroit Tigers Team Signed Baseball with the key signatures: Kuenn, Kaline, Bunning, and Martin is worth about $300-$450. 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. I do not have any information on a recent auction for a 1958 baseball but In a recent auction a 1957 Detroit Tigers Team Signed Baseball sold for $784. The signatures on your baseball are not authenticated. signatures that are not properly authenticated could sell at half the market value or less.
