How much is my nolen ryan baseball worth

Hi, jjctgl!

If you click on the following image search, you should get a rough idea as far as the possible monetary value by clicking on some of the images.

Signed Nolan Ryan Baseball - Google Image Search (http://images.google.com/images?hl=en&um=1&sa=1&q=Signed+Nolan+Ryan+Baseball&btnG=Search+Images&aq=f&oq=)

Is it an original signature?

Thanks!
