The US Mint shipped 8.4 billion pennies for circulation in 2017, more than all nickels (1.3 billion), dimes (2.4 billion), and quarters (1.9 billion) combined. [1] While countries such as Australia, Canada, and New Zealand have phased out their one-cent pieces, Harris Poll found that 55% of Americans are in favor of keeping the penny and 29% want to abolish it. [2][3]
The US Mint produces coins as instructed by Congress, so a law would have to be passed by Congress and signed by the President in order for pennies to be removed from circulation. [4] Several unsuccessful legislative efforts have sought to bring about the penny’s extinction. Most recently, in 2017, Senators John McCain (R-AZ) and Mike Enzi (R-WY) sponsored ultimately failed legislation that would have suspended minting of the penny. [5]
