Someone just turned what could be the world's oldest cracker into the world's most expensive cracker.

The last-surviving cracker from the Titanic in 1912 sold to a Greek collector Monday for approximately $23,000 at a British auction, according to UPI. It's now being called the "world's most valuable biscuit."

The cracker was reportedly part of the survival kit from a Titanic lifeboat and was kept by James Fenwick, who was a passenger aboard the SS Carpathia, which helped survivors of the Titanic more than 100 years ago.

'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," auctioneer Andrew Aldridge told the Salisbury Journal.

A photo of the iceberg that sank the Titanic more than 100 years ago — taken aboard a boat that passed after the accident — also sold for about $32,250, according to UPI.
