Call it the Heart of the Sea Biscuit.
Following an auction Saturday, a solitary cracker that survived the sinking of the Titanic sold for nearly $23,000 — which probably makes it more valuable than the (fake) "Heart of the Ocean" gem that ended up in the water at the end of James Cameron's 1997 movie.
"It is the world's most valuable biscuit," auctioneer Andrew Aldridge told the Salisbury Journal.
The cracker (known as a biscuit in the UK) was reportedly part of a survival kit stored with the doomed ocean liner on a lifeboat. It was kept as a souvenir by James Fenwick, a passenger on the SS Carpathia, which aided survivors of the ship, which sank in 1912.
The cracker was purchased by a Greek collector, wrote the BBC.

This isn't the only super-long-lasting food item to be auctioned off; a cracker from one of polar explorer Ernest Shackleton's expeditions sold for about $2,300 in 2011, and there's another cracker from the Lusitania in an Ireland museum.
"We don't know which lifeboat the biscuit came from, but there are no other Titanic lifeboat biscuits in existence to my knowledge," added Aldridge. "'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."
As the British might say, this really takes the biscuit!
