A pair of biscuits dating to the first world war achieved £340 ($578) in a sale at Lockdales in Suffolk on June 19, an increase of 466% on a £60 ($100) estimate.
It is thought British lieutenant Lionel Bruce Charles brought the biscuits home from the offensive at Suvla Bay in 1915, part of the Battle of Gallipoli.
Oliver Miller, a spokesperson for Lockdales, told the BBC that the biscuits are "the sort of thing any First World War period collector would love to have".

"They're probably still edible, if you really wanted to eat them."
He went on: "The biscuits were usually crushed up to put in tea or stews - they were so solid they didn't really like to eat them as a straight biscuit.
"A collector would love to own them and would probably just enjoy looking at them, maybe with a different pack of biscuits."
