What did I get into?

[masonm1]

Hello all! I'm brand spankin' new to this, so humor me as much as you will.
Recently purchased an estate and inherited quite a lot of baseball memorabilia.

I Have LOTS of Negro League items, including a poster with 210 signatures on it... That's gonna be a fun one.

What caught my eye to start this project was the signed balls. Here's what I got:

Mickey Mantle auto'd ball
Toni Stone, Mamie "peanut" Johnson and Connie Morgan auto'd ball
Leon Day auto'd ball
Satchel Paige and Roy Campanella auto'd ball
Cal Ripken Jr. Consecutive games played auto'd ball
Joe DiMaggio auto'd ball
Pete Rose auto'd ball
Monte Irrin auto'd ball
Cal Ripkin Jr. and Sachio Kinugasa consecutive game streak auto'd ball

Added pic's of said poster with 210 auto's from Negro League, thoughts?

Have CoA's to all items as well.
Pete Rose from The Score Board Inc.
Monte Irrin from Moody's Collectibles, Inc.
Sachio Kinugasa/Cal Rip Jr. from The Score Board
Toni Stone, Connie Morgan, Mamie Johnson from Wayne and Mike Stivers "Mister Sports Collectible"
Cal Ripken Jr. from The Score Board
Satchel Paige & Roy Campanella from Midwest Forensics
Joe DiMaggio from Pro Sports Services
Leon Day from Wayne and Mike Stivers "Mister Sports Collectible"
Mickey Mantle from Madison Sports Management
So, what did I just get myself into?
