It can never be said that auctioneers Henry Aldridge & Son never fail to see a profit in any Titanic memorabilia. A biscuit that was part of a survival kit in one of the Titanic lifeboats–and put into a Kodak photograph envelope by a passenger on Carpathia–is up for auction on 24 Oct 2015. The estimated price is between £8,000 – £10,000. Henry Aldridge tells the Daily Mirror:

“It is the world’s most valuable biscuit.We don’t know which lifeboat the biscuit came from but there are no other Titanic lifeboat biscuits in existence to my knowledge. It is incredible that this biscuit has survived such a dramatic event – the sinking of the world’s largest ocean liner – costing 1,500 lives.”

It really does prove Hard Tack can last a very long time indeed.
