Sorry guys if this has been addressed before but I searched the forum and could not find anything on it. I was curious to know what the general opinion was regarding signatures on game used items and the affect on the value of the item(s). I'm speaking more about uniforms, helmets, etc., not so much balls and bats.

I've got some unsigned football related items that I've had for some time and just started researching ways to contact individuals and gain signatures. That said, I wasn't sure if it was a worthwhile exercise or not. Although my intitial thoughts are that it would be, I wanted to get some opinions from fellow collectors. Any insight or advice would be appreciated.
