A Walter Johnson single signed Baseball is worth about $4,000.-$8,000.
Value is based on average prices of recently closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the signature. Signatures that have not been properly authenticated could sell at half the market value or less. Add for inscriptions. If the baseball was used in the 1924 World Series it could lower the value based on condition. A clean white baseball would be most preferred for the signature. Without being able to prove the baseball was used in the Series it would just be a vintage used baseball. If Johnson inscribed the baseball "1924 WS" it will have added value. In a recent auction a Walter Johnson single signed baseball sold for $3,585.00
