Canada's rarest coin is coming to Ontario this weekend for its first public appearance in Canada in almost 30 years. The 1911 silver dollar will be displayed at a coin show in Mississauga. The rare coin is one of the two silver dollars first minted for Canada.\nThe 108-year-old coin is known as the "Emperor of Canadian Coins" and is a rarity because only two of them were made. The showing of the coin will be at the National Postage Stamp and Coin Show in Mississauga this weekend.\n"It has a lot of mystique about it. It is Canada's most famous coin," Sandy Campbell, owner of Nova Scotia's Proof Positive Coins and owner of the coin, told Narcity.\nCampbell and Ian Laing, owner of Winnipeg's Gatewest Coin, acquired the 1911 silver dollar at an auction this August for only $734,000 when it was estimated to sell for over $2 million.\nIf coin was from the U.S., Campbell knows it would easily be worth $10 million because that's how significant it is.\nIn 1910, the government of Canada decided to strike the first silver dollar for the country, which had been happening in the U.S. for a hundred years at that point.\nThe next year the Royal Mint in England produced two copies of a silver dollar for approval but the government decided not to go forward with mass producing the silver dollars.\nFor years after that the Royal Mint had only one of the silver dollars in its possession. But it was known that two copies were made.\nIt turned out that a the former master of the mint had the other coin the whole time and it only came to light when a coin company bought it from his family in 1960.\n"It has always been a very desireable and sought after coin," said Campbell.\nAccording to a press release, "The other 1911 silver dollar has been held in the Bank of Canada's National Currency Collection in Ottawa – on loan from the British Royal Mint – since the 1970s."\nSandy Campbell | Point Positive Coins Ltd.\nCapmbell originally bought the coin in 1988 and when it was in his possession was the last time it was ever viewed publically in Canada.\nAnd now that he has the coin, him and Laing want it to stay right here.\n"The coin is not going to leave Canada again," said Campbell. "It's just too important and too significant for it to leave our borders."\nYou can see this Canadian rarity from 10 a.m. to 5 p.m. on Saturday and from 10 a.m. to 4 p.m. on Saunday.
