Charlie Sheen revealed as owner of storied Babe Ruth memorabilia

Not only does Charlie Sheen possess tiger blood, he appears to be the sole holder of two of the most coveted pieces of Babe Ruth memorabilia.

The avid baseball fan and longtime actor confirmed Monday that he cosigned Ruth's 1927 World Series ring, as well as the original and widely remembered sale document that sent Ruth from Boston to New York in 1919, according to ESPN's Darren Rovell.

Both items are currently up for auction on Lelands.com, as bidding for the ring has already surpassed the $600,000 mark, making it the most expensive sports championship ring ever.

The original document, meanwhile, is going for over $400,000. A previous copy owned by former Red Sox owner Harry Frazee sold for $996,000 in 2005.

"I've enjoyed these incredible items for more than two decades and the time has come," Sheen said. "Whatever price it brings is gravy."

Sheen, who said he's been in possession of both items since the early '90s, kept both pieces of memorabilia in terrific condition and said he wasn't sure how much he initially paid for them.
