A letter written by a famous Titanic passenger, just days before the ship sank, has sold for nearly $400,000 at auction.

The letter, written by first-class passenger Archibald Gracie, sold for five times its expected price at auction. It was written aboard the ship five days before it sank.

Letters written aboard the Titanic with the boat's letterhead are understandably extremely rare. The previous record for a Titanic-written note was an unsent letter by first-class passenger Alexander Oskar Holverson, found on his body, which sold for a record $166,000 in 2017.
