In the Charlton Standard Catalogue of Canadian Coins, the 1911 $1 coin is valued at $1,250,000. There are only 2 known specimens in sterling silver, and one specimen in lead. One of the silver specimens and the lead specimen are located at the Bank of Canada's currency museum, while the other is in a private collection. The rarity stems from the fact the federal government chose not to proceed with producing a "silver dollar" in 1911. The 1911 coin sets were originally planned to include the $1, but the sets came with an empty gap where the $1 coin was supposed to be. Canada didn't issue a $1 circulation coin until 1935, when it issued a circulating dollar commemorating George V's Silver Jubilee.
