When adventurer Captain Robert Scott packed a bar of Cadbury chocolate among his rations for his pioneering exploration of the Antarctic in 1901, he could never have guessed that a century later the same bar would fetch nearly US$1500 at auction.

Preserved in a cigarette tin, the 10cm bar was among the 1587kg of chocolate and cocoa Scott packed into his ship, The Discovery, for the three-year trip.

Experts have commented that high-energy contents and durability would have made chocolate a perfect choice for Scott’s sledging teams.

Last month, a 1937 Hershey chocolate bar was discovered buried near the South Pole.
