Celebrity and Sports Arena autographs from 1998
 

Hello, I am new to this site. When I was in Vegas back in 1998 I purchased a Pete Rose, Mike Tyson and Muhammad Ali autograph which cost me about $1000. Each came with a Celebrity and Sports Arena Certificate of Authenticity with a Certificate number, M/C code No. and a Embedded stamp from Celebrity and Sports Arena. I just want to know if they are legit or how I can look up these certificate numbers or M/C codes to see if these autographs are legit? I didn't care when I purchased them as I just "assumed" they were legit. What's the best way to see if these autographs are legit?
