I have a Willie Mays Autographed Baseball from his "Say Hey Authenticated!" website and comes with the special hologram. The ball is guaranteed to be the real deal and it was authenticated by PSA/DNA. I am asking 200.00. It is supposed to have a retail value of 450.00 but I am not a real big baseball fan and I thought that someone else might treasure it more. Ive included a picture so you can see what you are getting. Let me know if you have any questions.
