Welsh Tokens of The Seventeenth Century.

George C Boon (editor) 1973, published by the National Museum of Wales, with an Introductory Essay and a Mercer's Inventory of 1673.  PB 144pp + 4 page 1976 supplement. 

More than just a catalogue - the introductory essay is excellent.  All the tokens are illustrated.  Has a wealth of information.  This is the standard reference work on the subject.

Out of print.  About an inch of the top of the spine breaking off, and cover slightly marked, otherwise internally good.
