A 1965 Houston Astros Team Signed Baseball with the key signatures: Staub, Morgan, Fox, and Roberts is worth about $150.-$225. 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 don't have recent information on a 1965 Houston Astros Baseball, and the price above might need to be up dated but should be close. In a recent auction a 1968 Houston Astros Team-Signed Ball sold or $144. If the signatures are not properly authenticated the baseball could sell at half the market value or less.
