Ralph C Gordon.  Published by Erik Press, 1987.  HB (dark burgundy rexine with gilt-lettered front cover). 122 pages, illustrated throughout with b&w photographs.  Cites the relevant legislation, lists the host coin(s).  Has a bibliography, and estimated prices (1987), and an index to countermarks, including those of unknown origin.  It is the standard reference work on the subject. No 51 of an edition of 500.  No dj (as published). A tiny rub to top right corner, otherwise almost as new. Scarce.

Erik Press  - ERIK was the name of the group of specialist collectors who collected coinage of the West Indies, particularly the countermarked issues.  The name comes from the first letter of the christian names of the principal collectors - they are listed in this order at the top of page 8 of the 'Acknowledgements' section.
