The Heath Counterfeit Detector was enthusiastically produced over many years and sold tens of thousands of copies few of which seem to have survived. Numismatist Eric P. Newman did the authoritative work on the many editions and varieties of this work, covering 13 editions on over ten pages in his reference on the subject. We offer an example of the first edition from 1864, Newman's variety 1-P-1.5, with dated title page and one page of recommendations in the rear the lastest dated June 23, 1864. This first edition containing 8 plates continued until the fourth thousand (Newman's 1-P-4) when a two more tipped in plates were added (for a total of 10) plus an additional page of explanatory text.
For those interested in microscopy and scientific instruments Heath also sold a microscope to be used in counterfeit detection. All of Laban Heath's work is collected seriously in the numismatic world, and in the book world for its value in understanding counterfeiting and crime as well as the use of fine engraved printing for such a task.
