Address used is the Yankee's address on the database here. I would think sending a jersey would be fine, in a larger package (those he apparently signs first).

How about a jersey? Anyone ever have a success with a jersey? I have seen a post in the past stating people have better luck sending a bigger item rather than a card or something small. Mariano seems like an awesome signer for his fans and I would love to send him something.

whats the address used?

He will sign up to 2 items per package but I would not send 2 baseballs. I sent him a ball and a ticket and got both back signed. If you want them quickly, send it in a larger padded envelope and send them priority mail (got it back within 7 days!)

All right, thanks for responding!

He signs for free. Two baseballs in one package might turn him away from it though. There have been people who have sent two different items, like a ball and a ticket or a ball and a hat and received both items signed. Shipping, I know, with an SASE and a baseball all in the same envelope is about 7$ via UPS.

My dad and I are huge fans of Mr. Rivera, I'm thinking of sending two balls to him to sign one for me and one for my dad. I need to know if he's actually going to sign both of them. And if he is going to, how much it would cost me. Thanks!
