How much is a baseball worth signed by both Aaron and Mays?

Answer 1

The value of multi signed baseballs cannot be priced by the value of each signature added up. Multi signed baseballs are valued as a group of signatures, and how desired that group is as a whole. This does not necessarily mean that two signatures will sell for less than one, but in most cases it does, or at least not the full value of the two signatures added up.

A Hank Aaron single signed Baseball is worth about $200.-$250. A Willie Mays single signed baseball is worth between $150.-$200. The value of a Hank Aaron Willie Mays dual signed baseball should be between $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. Signatures that have not been properly authenticated could sell at half the market value or less. In a recent auction a Hank Aaron Willie Mays dual signed baseball sold for $155.35
