A pair of rare Rs 10 banknotes, which 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 Rs 10 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.
