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.
