While there wasn't a Canadian Silver dollar in 1930, there were Dominion of Canada 50 cents silver coins circulating therefore a pair of 50 cent halves would be worth $19.24 USD or $27.60 CAD that would buy me a little more 4 dozen eggs at the local Real Canadian Superstore today. The closest Canadian Voyager silver dollar is the 1935 George V.
Indeed, moral of the story is stack silver. Thanks for your perspective @kerrislravenhill.
