The tin was recently found a Lincolnshire attic among in a box of junk, Metro reports.

Made in 1899 during the Boer War to send to soldiers, the tin of chocolates, a Rowntree’s product, contains several bars of chocolate. They are unlike modern confectionary which would have long spoiled.

Expecting to fetch £100 to £200 at auction, the seller was happily surprised with a final sale of £440 (rising to £512 after fees).
