“I love silver; I always have,” said Beaver Bullion founder and owner John Masterson, who’s a member of the Royal Canadian Numismatic Association; Ontario Numismatic Association; Canadian Association of Token Collectors; Toronto Coin Club; and Canadian Centennial Collectors’ Club. “The way if feels, the way it sounds, the satisfying heft it has when you are holding it in your hands has always appealed to me.” Beaver Bullion is Canada’s only hand-powered silver company. A long-time collector, Masterson has more than 30 years of hobby experience. “I was sorting pennies when I was 10 years old,” he said, adding he now specializes in exonumia, trade dollars, 20th-century Canadian medallions and silver bars. “I like collecting silver bars, and that’s how I actually got into pouring silver: I wanted to figure out if I could actually do it for myself because it’s fun to collect, but sometimes it’s also fun to get your hands dirty and make something.”
