In 1984 and 1985 the National Postal Museum decided to auction a quantity of material they deemed to be duplicated and surplus to requirements. At the time, concerns were raised about selling and that the curators should act as custodians and conservators, retaining all the material in trust for future generations to study and enjoy. The first auction, which took place in April 1984, was restricted to G.B. and G.B. overprinted Colonial issues of the reigns of King Edward VII to King George VI and included regular issues overprinted "Specimen" as well as imperforate imprimaturs.
