The 400th Anniversary of the Discovery of Hudson's Bay, a 2010 gold proof 100 dollar coin from Canada.

This 2010 gold proof $100 coin celebrates the 400th Anniversary of the Discovery of Hudson's Bay by Henry Hudson, who explored the bay in 1610 on his ship, the Discovery.

John Cabot… Martin Frobisher… John Davis… Henry Hudson. More than a century after Cabot, Hudson began his quest for the elusive northwest passage to Asia. After three failed attempts, Hudson sailed for Iceland in 1610. From there, he crossed Davis Strait into the treacherous waters explorers called the Furious Overfall (modern-day Hudson Strait). After months of turbulent, ice-filled water and jagged reefs, the strait opened up. Hudson believed he had reached the Pacific Ocean, but he was mistaken; Discovery was in a vast inland bay that looked deceptively like the open sea. The Spice Islands were still out of reach, but Hudson had far outdistanced his predecessors—and his discovery proved to be of immeasurable value by opening up the continent’s interior to England’s expanding fur trade.
