James A Mackay. Published by the Pobjoy Mint, Sutton, Surrey, 1979.  PB 2nd edition. 84 pages, including 8 colour plates; also illustrated in the text in b&w. Lists both coins and tokens. Appendix 7 is a 2 page listing of jetons, counters and miscellaneous tokens by Alan Kelly.  A very good clean copy, almost as new.  

The colour plates illustrate the minting process from the designing of the coin, the preparation of the blanks, to the striking process, counting, weighing, bagging, etc. 

There is some mystery about the dating of this book. The front cover says 1979, the title page says 'second edition' 1978, and the next page says 'copyright 1976'. It is also billed on the front cover as 'Millennium Year'.  Take your pick !
