The Piano Played by Humphrey Bogart in Casablanca

The piano from "Casablanca", one of Hollywood's most romantic films, was auctioned off for $3.4 million on Monday, November 24th, 2014 to an undisclosed buyer in New York. It also places tenth in the list of most expensive memorabilia ever sold. Bonhams, the auction firm in charge of the sale, will receive a 12 percent commission. For someone ready to pay this much for a piano, you'd think it would be in perfect shape, but it has a wad of chewing gum stuck to the underside of the keyboard.

This timeless item is golden yellow with Moroccan green and gold accents. Instead of the standard 88 keys, this piano has a 58-key keyboard. The piano appeared on the screen, with Humphrey Bogart listening and Dooley Wilson playing it. Wilson did not play the piano, but tinkled the tune on the keyboard. Humphrey Bogart hides the letters of transit in the piano, which plays a key role in the film. The piano is the epicenter of the café's activity.

Price: $3.4 million
