Published to commemorate the 50th anniversary of decimalisation in February 2021, this compact book gives a general introduction to the biggest reform to the UK currency in its 1500-year history. The planning and implementation of decimalisation is covered from different angles including the role of the Decimal Currency Board, the production of new coins at the Royal Mint, as well as the preparation of businesses and the public for 'D-Day'. Combining political and social aspects of the currency reform, it contextualises important moments and key challenges within a clear and compelling narrative. Featuring exclusive interviews and profiles of the people involved - from shop workers to the designer of the coinage - this entertaining book will immerse the reader in early 1970s Britain, at an important moment in its history.
