I have this...no, it IS NOT available...

My question is this...I got this signed by Mickey Mantle in person during a show back in the 90s in Texas. Back then certificates of authenticity weren't as huge as they are today so I don't believe I got one (If I did it's not with the auto now). Is there somewhere I can send it to to get it certified?
This may be a dumb question but I don't deal much with autographed memorabilia.
Thanks in advance!
