From 2003 to 2012, Canadian one cent coins continued to feature Queen Elizabeth II, with an updated effigy by Susanna Blunt introduced in 2003. This design showed a more contemporary portrait without a crown, signifying a modern representation of the Queen.
The reverse remained unchanged, still showcasing the iconic maple leaf design that has been a staple since 1937. During this period, the coins were made primarily of copper-plated steel, consistent with the materials used since the late 1990s.
Collectors are particularly interested in these coins due to the updated portrait and the final years of the penny's production. The discontinuation of the Canadian penny in 2012 marked the end of an era, making these coins a significant part of Canada's numismatic history.
