Auto'd Yankee ball Need pricinig help

easydoesit

A co worker brought me a 1985 Yankee team ball with a few sigs on it. They got it in Toronto before a mid summer game. The sigs are Phil Niekro, Billy Martin, Lou Pinella, Rich Bordi, Dale Berra, Ed Whitson, Dave Righetti, and Ron Guidry. I told him probably between $50 and $100 with two hall of famers. Ball point pen sigs, but they are still in good shape and the ball is clean. AM I in the ball park? Do you think that is accurate?

Thanks
Chris

$100-150 for a Billy single signed ball. BTW Niekro is the only HOF on the ball.
