A pair of rare 10-rupee banknotes that were recovered as they floated away from a shipwreck on their way from Bombay to London in 1918 are to be auctioned next Wednesday. Noonans Mayfair auction house in London will offer the notes as part of their World Banknotes sale and are estimated to fetch between GBP 2,000 and 2,600. 

The two 10-rupee banknotes were recovered from the wreck of the SS Shirala, which was sunk by a German U-boat on July 2, 1918, and bear the date of 25 May 1918 on them. “Whole blocks of these notes were on their way to Bombay from London when the boat was sunk,” said Thomasina Smith, Worldwide Head of Numismatics at Noonans.
