The Baseball Stars

I have been collecting autographs for a good amount of time and am looking to sell some of them. I was thinking about ebay, but would rather not. Some of the autographs sell way under priced. I am also unsure what some of my more prized autographs can go for. Such as a book/pamphlet signed by the 1964 Cleveland Browns and a Signed Mini Helmet of LaDainian Tomlinson. Also signed baseballs by Manny Ramirez,Pedro Martinez, and Derek Jeter. I have a wide variety of signed memorbilia from many different players. So basically any info would help.

Thanks,
Mike
