I bought a few Canadian coins/tokens in his Heritage auction a few years ago. Maybe coin collecting contributed to his longevity. He was 106 !
Eric Pfeiffer Newman (May 25, 1911 - November 15, 2017) was an American numismatist. He wrote several "works about early American coins and paper money considered the standards on their subjects", as well as hundreds of articles. Newman sold his coins over five auctions in 2013-2014 for almost $55 million.
