6 Cabin Master Key – $138,000
The master keys owned by a first class steward, named Edmund Stone, for a series of cabins.
Stone tried to escape along with the 15,000 others during the sinking.
They recovered the keys off his body later and returned to his wife back in the United Kingdom.
Although he died back then, the keys were recovered and were bought by an American collector for a little bit over $138,000 at Henry Aldridge in 2008.
The keys were one of the most expensive items of Titanic memorabilia.
