Every few months Americans gather here to argue this same question, over and over again.
Every time, people from other countries (such as Australia) where the smallest coins have been removed from circulation come in to offer actual observations about what actually happens when a country does the very thing that Americans are arguing about.
Every time, the dirty furriners are ignored and the Americans continue to argue the same stupid shit back and forth endlessly.
Here’s what happens: nothing. Prices are rounded, you gain about the same amount you lose, and the net benefit of no-one having to mess around with practically worthless coins is considered a profit by everyone. Life goes on, much the same as before, and even the people who argued most for keeping the 1 and 2 cent coins got over it and moved on with their lives and nowadays no-one wants them back.
But, of course, since that didn’t happen to Americans, it didn’t really happen at all.
OK, continue your arguments.
