1994 Orioles Baseball question

Hello, When I was a kid I got tickets to be "Honorary Batboy" at Camden yards. I basically got to sit in the dugout with the players the whole game. While there I got several autographs on a baseball including the following:

Cal Ripken
Billy Ripken
Raph Palmaro
Brady Anderson
and several others.

Later I was able to get the signature of Cal Ripken Sr. on the ball as well

I would like to save this ball to hand down to my kids but would like to know what the best method of getting the ball authenticated would be. I'm sure its worth something now but I have no idea if I should put insurance on it or what I should do.

Thanks.
