US Treasury to stop producing pennies next year

Australia stopped one and two cents coins decades ago. It's sad to have to live with a system where the numbers are just two or even five times larger than they should be, but I suppose worse things have happened.

Replace it with a 33 cent coin

It's about time.

Andy Rooney complained about pennies back in the 1980s. https://www.youtube.com/watch?v=A-zcWgXu4hg . "A penny saved is a waste of time."

In inflation-adjusted terms, a penny back then was worth almost 3 cents now.

I am such a cheapskate that I can't not bother with pennies. I will save so much time from this.
