Mintage of this coin is limited to just 2,150. As a pure silver coin issued by the Royal Canadian Mint, this coin is HST/GST exempt. The Design:The design originally created by renowned artist and sculptor Alex Colville presents a flying Canada Goose, symbolic of Canada as being “serene and dynamic”. While the original 1967 version was struck in just 23 grams of. 800 fine silver, this new 2017 version has grown to a 65 mm diameter with a weight of just over five ounces (157.6 grams) of pure silver. The finish on the Big Coin is the finest quality double struck proof, and the goose 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.
