Chunichi Dragons - 2 Autographed Balls

I'm not sure if these are authentic.
They were found in my parents' warehouse.
I don't know the value of baseball memorabilia, so I'm selling them.

Suzuki Player - Autographed Ball (Single)

Martin Player, Suzuki Player, Aoyama Player, Oshima Player
Autographed Ball (4 Players)
(Apologies if I've mistaken any of the players' names.)

There is yellowing due to age.
