Baseball/Sports Cards appraisal?

[colorider]

Pro graded as mint. 10. Authenticated and in plastic cases. This guy is no hobby collector. It’s his life and income. And his dad was a collector as well and he owned his dads collection. Think mint condition baseball cards from the old days. All the greats. It’s AMAZING. All I will say is his basement is mind blowing with what he has. Should be in a vault or a museum. It doesn’t end with sports cards. Music, movies, actors, actresses, you name it. Signed pictures dating all the way back to the original Superman!!!!!! From black and white films all the way to a freaking signed bowling ball from the cast of Big Lobowski.
This guy’s dad worked at panoflex, or panovision, or whatever the old time movie production company was. Then at 14, my customer started warming with his dad. Amazing stories.
