AUTOGRAPHS

What’s the best way to get a Ted Williams Autographed score card authenticated?

I have a score card that i know is authentic that was signed in 1941 by Ted Williams and a bunch of other players on his team.
Also what would something like this be worth once authenticated?

If you know that it is real why would you pay someone to tell you that it is real?
It is nice to have and has value. Keep it for yourself.
Authentication is a scam perpetuated by these so-called experts.
I have a number of autographs that I accumulated over time. I know they are real because they were signed in my presence by the player(I worked at a ballpark). I brought a few to a so-called expert who told me they were questionable?? Really, they were signed by a player in front of me.
So, be careful and save your money.
