Need opinions on a couple Jeters & Mantle/WIlliams Ball

Guy's & Gal's,
This is my first post & I am brand new to the forums, I have been reading them for a while & collecting for a couple of Years. I have obtained a couple of autographs through friends & local card shops that I think you guys mught have a better opinion on authenticity then myself. I get most of my autographs at local signings & card shops. Any input would be greatly appreciated good/bad or ugly. I also threw in a Tony Stewart card if there are any Nascar fans on here.
Thanks in advance

If you use this one for comparison
Note on the left of the card it says "Authentic Signature"
Here is the card you have.
Note on the left of the card it says "1 of 45,000"
I am skeptical of the signature. I don't think it is real unless it was signed by Jeter after the card was pulled from a pack.
I am no expert when it comes to authenticating autos... I have no idea if they are authentic or not.
On the Jeters, when Signature Rookies came out Jeter's signature was readable almost to every letter, so it's not likely they are NOT pack pulled. I'm not an expert on Jeter so I'll defer, but they certainly were not signed when the cards were issued.
Anyone have an opinion on the Jeter WS ball?
Thanks again for all your input.
