How much do you think this is worth.
 

I have a 1997 team-autographed Oakland A's official MLB baseball and I'm trying to sell it. This guy offered me $500 for it and he's being real rushy about the transaction. I wanna sell it but I wanna make sure I'm getting almost what it's worth. It's signed by the whole team including Mark Mcguire.

What do you guys think?

Why not just put it on e-Bay and find out?

Because right now I'm on the virge of being broke and have no money even for eBay. Also, everything on eBay sells cheaper than anything else.

Go to a collecters store and see what price they give you. I did that for a 1995 signed knicks team and got close to $600 dollars a few years ago. They know thier shit
