Cincinnati: (c. 1852). 8vo, original printed pictorial paper covers. 50, (6) pages; numerous coin illustrations. Front cover reattached with archival mending tissue. Very good. Item #6300
An early example of the genre, first published around 1848 by John Thompson, and widely emulated by other counterfeit detector publishers for years thereafter. Includes an 1851 Humbert U.S. Assay Office $50 slug, but does not list the 1853 silver issues with arrows. An unusual feature is that it includes two pages depicting Roman gold and silver coins in addition to the pages depicting more current coins of the world.
