The photos say it all - this is a MAJOR acanthite for any Canadian locality, let alone from the cobalt mines where few large specimens were ever found and saved. It is dramatic and well crystallized, with several habits present on the specimen. It was found in 1963 and sold by the miner to John Durkos: From the noted collection of John Durkos, who built the best-documented and most extensive collection of silvers and silver species from the Cobalt area mines during their times of operation. His collection was particularly noted for detail such as when the specimens were collected, which he tracked down with care in buying directly from the miners. His collection passed on to Richard Hauck in the 1990s, who sold this to a silver collector at that time. It has not before been offered for public sale and is, in my opinion, an important and historic Canadian specimen. This specimen masses 788 grams, or about 2 pounds in weight.
