GUEST: These are baseball cards that my mother has had for years. Her brother collected them.

APPRAISER: What you brought in is a very impressive group of 1950s Topps baseball cards. Really, surprisingly high amount of these that are in EX-plus, near-mint condition. It's all about condition in collecting. What you brought here, I would expect to sell at auction for $15,000 to $20,000.

GUEST: Ooh, very good. Very good.
