Alright. I'm not sure what side you're on, so I'll provide one for both sides:
1. Despite its insignificant monetary value, the US penny depicts one of the most iconic figures in the nation's history; preserving it is not a matter of sustaining its value, rather sustaining the way we remember our founding fathers.
2. As notable and iconic as it is, the insignificant monetary value of the US penny makes its production a waste of time and resources; there are other ways to celebrate the achievements of our founding fathers, but resuming the production of a nearly worthless coin is not a viable option.
Feel free to look at these and try to tweak them to your liking.
Today, there’s literally nothing you can buy with a single penny – and you can’t do much else with it either. Vending machines don’t accept them, and neither do most parking meters. Even automatic toll booths won’t take them except in Illinois, the home state of President Abraham Lincoln, whose face adorns the coin. So there is no point on having the penny around or having it preserved.
