DES MOINES, Iowa (AP) – An Iowa family’s collection of baseballs signed by slugger Babe Ruth just before he died has sold at auction for more than $200,000.  Heritage Auctions director Chris Ivy says eight balls signed by Ruth during a trip to Spencer in 1948 sold for just over $216,000 on Friday.  One ball in near-mint condition went for $77,000, while two others sold for just over $13,000.  Ivy says Ruth visited a Ford dealership in Spencer owned by John Hart 64 years ago. Hart’s family kept eight of the dozens of balls Ruth signed in a safe deposit box for more than six decades until deciding recently to put them up for auction.
