U.S COIN SCALES AND COUNTERFEIT COIN DETECTORS

Newman Portal Adds U.S Coin Scales and Counterfeit Coin Detectors

In 1999, Eric P. Newman and George Mallis teamed up to publish U.S Coin Scales and Counterfeit Coin Detectors. The authors begin with a history of scales for coins stretching back to the second millennium before Christ. The book comprehensively covers all scales and counterfeit coin detectors for which United States patents were issued, and many that never received patents. The authors focus on the experience of one inventor, John Allender, who, after many tries, was finally able to secure a patent for his machine, which combined high accuracy with a low price, and thus became successful in the marketplace. This work has recently been scanned by Newman Portal and is now available online.

Unlike most other Newman publications, this title was self-published. Newman had four hundred copies of the book printed in early 1999 by Creative Printing Services in St. Louis; these were marketed at $39.50 per copy beginning in March of that year. Newman noted in correspondence to Mallis on September 29, 1998, The pages will be printed on 2 sides because the bulk of the book if printed on one side would be too heavy and difficult to read. Illegal photocopying of our pages will be much more difficult if printed on two sides (this, obviously written before two-sided copying was ubiquitous). Sales were slow, with just over a hundred copies sold by the end of the following year. Newman's unsold books were ultimately distributed by numismatic booksellers Kolbe & Fanning, where they remain available for those desiring a hardcopy.
