In Canada pennies have disappeared from cash transactions completely... The amount is rounded up if it’s 3... Down it’s 2... Electronic transactions still maintain the exact amount of the transaction. No rounding up or down.
I have wondered why they just don’t revaluate new mintings of the penny coin to 3 cent value (not eliminate the decimal .01 value from our financial transactions).
Australia eliminated their one-cent and two-cent coins in February 1992. The coins were withdrawn from circulation because their value was very low and the cost of producing them was more than their face value.
