The 1oz Canadian Maple Silver Coin is a pure .9999 silver coin, making it the purest silver coin available. It was first minted by the Royal Canadian Mint in 1988 and is issued annually. It also has the highest face value of all silver coins. For sale: singles or tubes of 25. Dealers throughout Australia are selling them for up to $53 dollars each. Also very, very few have stock and there are long waiting lists. My price is $43 for singles and $995 per tubes. F2F Brisbane, Gold Coast, Sunny Coast. Postage not included but can be arranged.
