The latest publication on So-Called Dollars by Jeff Shevlin and Bill Hyder, So-Called Dollars Volume I – United States Expositions, is a new standard reference book for So-Called Dollars, historical U.S. medals. The book catalogs So-Called Dollars from 67 different expositions held in the United States, from the 1853 New York Crystal Palace through the 1964 New York World’s Fair. It includes detailed information never published before. The book is heavily illustrated and printed in full color to make identifying and cataloging your so-called dollars as easy as possible. The cataloging system includes the new SH number, composition/variety, rarity, weight, diameter and a cross-reference to the old HK numbering system where applicable (although there are an extensive number of new pieces not listed in the HK system).
