I normally only send out ball cards I collected back in the 80's and 90's. But I might try sending out a baseball or two now that I'm starting to get a few of my first batch back. Does anyone have any suggestions on who signs baseballs? And on average how much does it cost?

Here's another rookie question...with the correct postage, can I just put it in my mailbox or do I have to go somewhere like fed ex?

Thanks for any help you're able to offer me.
