The autographs are not been authenticated so the ball is priced accordingly. However, I will give you 100% of your money back if a reputable authenticator such as PSA/DNA, JSA, or even Global deems these autographs are non-authentic (must show proof with failure documentation). Moreover, I have been selling stuff on Ebay for over a decade, and I can proudly say that I had NEVER had an authenticity problem. So bid with confidence.
