The new coins incorporate advanced security features and are manufactured with the mint’s patented multi-ply plated steel (MPPS) technology. They retain the common loon and polar bear designs and physical appearance. Existing $1 and $2 coins remain legal tender and will continue to circulate alongside the new coins. These coins “set new standards in cost-effectiveness, durability and security,” said Ian E. Bennett, RCM president and CEO.
