1970 represented the 100th Anniversary of the Manitoba Province of Canada. In 1869, under the Rupert's Land Act of 1869, the Hudson Bay Company (HBC) sold their rights to its massive Canadian land holdings. In 1870, the agreement was consummated with a payment to HBC and the Manitoba region was the first area to be accepted into the Canadian Federation as a Province.
To commemorate the occasion, a circulating commemorative with a nickel composition was authorized for minting.
The obverse, designed by Arnold Machin, features the bust of Queen Elizabeth the II facing right. On the outer periphery are the words “ELIZABETH II” and "D. G. REGINA" which is the abbreviation for the latin term Dei Gratia Regina or By the Grace of God, Queen. Surrounding the overall design is a circle of beads.
The reverse, designed by Raymond Taylor, prominently features a floral design of a prairie crocus in bloom. The Designer's initials “RT” are located in the center of the design just below the stem of the center flower. On the upper outer periphery are the words “MANITOBA” and the dual date “1870 1970”. On the lower outer periphery is the word “CANADA” and denomination “DOLLAR”.
