Russ Logan was keenly interested in the "third die" used for production of our coinage. This was the edge die or collar. During the course of his numismatic study, he desired the capability of photographing the edge of various coins in his collection. As an engineer, he designed these edge mirrors and had them produced by his company, Inovent Engineering. Development of these edge mirrors was described in his paper "The Third Die: A Different Look" appearing in America's Silver Coinage 1794-1891 presented at the 1986 ANS Coinage of the Americas Conference.

This lot contains a selection of these edge mirrors. Through arrangement with Mrs. Brenda Logan, all proceeds of this lot will be donated to the treasury of the John Reich Collectors Society. Of course, we will also donate the 15% buyer's premium to the club treasury as well.

Thanks to all who participated in this offering of coins from the Russell J. Logan Collection.
