coins using these effigies are similar to those used on other Commonwealth coins of those periods. The 1990 and 2003 effigies were designed by Canadian artists: Dora de Pedery-Hunt designed the 1990 effigy, and Susanna Blunt designed the 2003 effigy. Although these designs are the basic pattern for the coinage, the Mint regularly introduces commemorative coins, either for the entire series of coins, or on individual coins. Those commemorative issues are normally for a limited time period. Notes The current complete series of notes, known as the Frontier Series, is the seventh series of notes issued by the Bank of Canada. It consists of five notes: a five-dollar note, featuring Prime Minister Wilfrid Laurier a ten-dollar note, featuring Prime Minister John A. Macdonald a twenty-dollar note, featuring Queen Elizabeth II a fifty-dollar note, featuring Prime Minister William Lyon Mackenzie King a one hundred-dollar note, featuring Prime Minister Robert Borden The different denominations of the Frontier Series were released individually, starting in 2011. The notes are made of polymer, rather than paper, and contain a number of anti-counterfeiting measures, such as holographic features and transparent sections. A new eighth series of notes began release in 2018. only one note in the new series has been released, a ten-dollar note featuring Viola Desmond. Withdrawn coins and notes All of the previous Dominion notes issued by the Minister of Finance, and notes of all former series issued by the Bank of Canada, are gradually withdrawn from circulation when a new series issues. That process can take some time. For example, the Minister of Finance only issued one series of one-hundred-dollar Dominion notes, in 1871. The last time a $100 Dominion note was turned into the Department of Finance was in 1918. In addition to that routine withdrawal from circulation, there have been other withdrawals when a coin or note no longer serves a purpose: the penny was withdrawn from circulation in 2013, because its value had depreciated so much it did not serve any true commercial purpose. Change for cash transactions is now rounded up or down to the nearest five cent. there has only been one twenty-five-dollar note, the Silver Jubilee note marking George V's twenty-fifth year on the throne, issued in the 1935 series. It was withdrawn from circulation on an ongoing basis. there has only been one five hundred-dollar note issued by the Bank of Canada, in the 1935 series.
