What's my baseball worth?

[fd24]

I was given a baseball in a plastic case that has a number of autographs on it. It appears to be a 1970's ball since it is a National League ball and William D White was the pres. Appears to be east coast major leaguers (Philadelphia?).
Al Brancato
Ted Kazanski
Don Money
Ed Sanicki
Lou Brissie
Benny Culp
and probably 10 more that I can't be sure of.
May be from an old timers game ??? Anyone got any ideas?

Interesting item. An old-timers game might be possible, but it seems doubtful. Most of those players seem a bit obscure for most old-timers formats; besides, Money was still active into the 80s.

If I had to guess (and that's all this is), I'd say that these signatures were collected on the same ball at different times (Philadelphia sounds like a likely site). Perhaps a collector brought this ball with him every time he went to the park, and picked up these autographs over the years?

As to its worth, it's hard to say. Probably not much (again, just guessing) since there aren't any big names (and probably no way of authenticating the signatures), but on the other hand, some of these signatures may be hard to come by.

In any case, definitely a nice, interesting ball!
