800 fine silver, this new 2017 version has grown to a 65 mm diameter with a weight of five ounce of pure silver. The finish on the Big Coin is the finest quality double struck proof, and the wolf has been enhanced with a layer of 24 karat gold, creating a spectacular work of numismatic art. Even the obverse portrait of Queen Elizabeth is special, featuring the effigy in use in 1967 with selective gold plating on the Queen's gown. Design: howling wolf, symbolic of the Vastness of Canada.
