Since the Titanic's tragic shipwreck in 1912, people around the world have wanted to preserve the legacy of not only the ship but its passengers, as well. For that reason, auctions focused on Titanic memorabilia have continued to garner attention for more than 100 years after the accident.

Titanic survivor Archibald Gracie's 1912 lettercard sells for £300,000 ($399,000), six times the expected price.
