What would make a baseball hat be worth $300,000?

Other big-ticket baseball memorabilia items that sold in Wednesday’s auction include a Joe DiMaggio 1937 baseball cap that fetched over $150,000 and a 1932 Yankees ball, signed by both Ruth and Lou Gehrig, which went for just over $115,000.

“I don’t have a crystal ball, so I don’t know what it will go for, but there are two types of buyers — collectors and investors — and it would be great for either. It’s a great investment which will go up in value over the years,” Siegel said.
