During the 1980s, chocolate producer Cadbury commissioned the royal goldsmith Garrard & Co to create thirteen 22ct gold eggs for a treasure hunt labelled Cadbury’s Conundrum.
A dozen were hidden at secret locations across the country, with clues to their whereabouts included in a book written by Don Shaw, while the 13th and largest was awarded to a Cadbury’s retailer. This egg is now being offered on the market for the first time in Batemans’ July 1 sale in Stamford.
