Either he signs for free or he charges. Obviously he signed it, but added his two cents too.
As amazing as this is to believe, not everyone is out to make a buck on this stuff, but as time passes, so do the owners of these items. Eventually a kid, brother/sister or a husband/wife ends up with something like this and really has no need/want for it. Aside from tossing it or donating it, the next logical step is to sell it.
Sure, there are also plenty of "dealers" who get free autographs to sell, but I can't believe they are the majority. I think every player should consider signing for free or ask for a modest fee, either for themselves or to give towards a good cause. I'd pay $2-5 for most players signatures I need, but when they want $10, $20 or even $100+, I start drawing the line, especially obscure players.
Nick,
I think you may have shared a story about Bob Giallombardo and him not responding to an autograph request after your interview. I also found one guy who said he charges $25 for a signature. The guy played 1 year, if that. Still, I would probably pay it now to get one, if I knew he would sign and I had the address. He won't be alive too much longer and then my opportunity is gone. He is one of a handful of 50s era Brooklyn Dodger players I don't have an autograph from. He is a $3-5 player in my mind though, but through his apparent stubbornness to sign, he has created a scarcity!
