A tin of Cadbury chocolates that has been perfectly preserved for 121 years will go to auction soon.<br /><br />The confectionery was originally given to nine-year-old Mary Ann Blackmore to celebrate the coronation of King Edward VII and Queen Alexandra on June 26 1902.<br /><br />Cadbury adorned the special tins of vanilla chocolates with the two monarchs to mark the event.<br /><br />Blackmore kept the chocolates in tact for her entire life; her family have now brought the treats to Hanson’s Auctioneers in Derby.<br /><br />Auctioneer Morven Fairlie said: “If you do open the tin, it does smell of chocolate, but I wouldn’t want to risk it.”
