Guys:
Thanks for the responses. The balls are all Official Game Balls encased and protected and received as a gift from my neighbor who knew a number of major league umpires who could get signatures. The signatures are in blue pen, easily read, and between the seams opposite the label, i.e. the American League or National League logo.
Fish - What is TUFF STUFF and how might I find a copy?
Fair Warning - Thanks for the info and your address. I'm totally in the dark as to the value of things that I have accumulated.
Winky - Sounds like the balls meet your criteria.
My neighbor has given me numerous other sports memorabilia such as photos of Joe Montana and Vince Carter with wet signatures as well as a Hawaii football signed by June Jones. He has incredible stuff like boxing gloves signed by Muhammad Ali, Sugar Ray Robinson, a hockey stick signed by Wayne Gretzky, photos signed by Mickey Mantle, Joe DiMaggio, Willy Mays, and on and on. He's 75 years old and had a lot of contacts over the years and built up quite a collection and cherishes them more than their value. Neither he nor I know what they're worth. Thanks again.
