Take a look at this baseball superfan's rare $30 million collection—including a $2 million Jackie Robinson jersey

Inside a $30 million private sports museum

Gary Cypres isn't just a baseball fan, he's a sports fanatic.

He's a former investment banker who has spent 30 years amassing a wealth of sports memorabilia in a 37,000-foot warehouse near downtown Los Angeles. The collection was estimated to be worth $30 million, when Cypres spoke to CNBC's "Secret Lives of the Super Rich" last year.

It is a museum of treasures — with usually just one visitor.

"Primarily, it is open to me," Cypres told CNBC in 2017. "I come every day."

Though the collection is normally closed to the public, CNBC's "Secret Lives of the Super Rich" got a rare look.

Cypres was first interested in memorabilia from the New York Yankees baseball team and expanded his collecting from there. "I was born in the Bronx, near Yankee stadium," he explained on "Secret Lives of the Super Rich."

But for fans of the Los Angeles Dodgers, who are competing against the Boston Red Sox in the World Series, Cypres's collection is sure to impress.

The single most valuable item in Cypres's collection when "Secret Lives" got a look was a Dodgers jersey game-worn by Jackie Robinson, which could fetch $2 million in an open auction, Dave Hunt, a sports memorabilia expert, said at the time. The Dodgers, originally headquartered in New York as the Brooklyn Dodgers, went west to become the Los Angeles Dodgers in 1957.

Cypres also had a Dodgers uniform worn by baseball legend Babe Ruth while coaching the team in 1938. According to Hunt, the uniform was worth about $500,000.

The collector had an entire room dedicated to Ruth, who was best known for his performance with the Boston Red Sox and the New York Yankees. Cypres's Babe Ruth cache also includes a fur coat and a shotgun once owned by the famed player.

In total, the collection of Babe Ruth history was worth over $1 million in 2017.

Also among his collection, Cypres had 20 World Series trophies, as well as a rare 1909 baseball card for Pittsburgh Pirate shortstop Honus Wagner, estimated to be worth between $300,000 and $500,000, according to "Secret Lives of the Super Rich" at the time.

The World Series is an opportunity for Cypres — a chance for more history to be made: "To a collector like myself, there is always tomorrow," he said.
