Question about a vintage baseball...
 

I've been searching around on eBay and noticed two different baseballs. I'm not usually into baseball memorabilia as much as the cards, but have a few questions pertaining these items...

1. Whats so special about them?

2. Where there a bunch of these made?

3. Why so expensive (based on autographs)?

Any help would be great!

thanks but
 

I guess I should have been more clear... I actually have a Yankees team signed ball with Ruth so I know those are expensive, but like you thought that price was excessive for the condition and wondered if the ball had anything to do with it...
