Why are the 1c and 2c coins no longer in use?

The 1 cent and 2 cent coins are no longer in use in several countries, including Australia and Canada, primarily due to their declining purchasing power and the cost of production exceeding their face value. As inflation increased, these coins became impractical for everyday transactions, leading to their withdrawal from circulation. Additionally, many consumers and businesses found it more efficient to round prices to the nearest five cents, eliminating the need for these smaller denominations.
