Dr. Tillich thanked his audience and promptly left the platform. He was sitting in his carseat and we were having a normal chat when he noticed the moon was out. Then he said.

Age is a question of mind over matter.
If you don't mind, it doesn't matter. United States dimes, quarters, and half dollars have notches all around their edges, but pennies and nickels have no notches. Notches are a remnant from days when the value of a coin was determined by the amount of silver or gold it contained. The US mint incorporated the notches as a way of discouraging people from shaving off small amounts of the precious metals from their coins. Less valuable coins have always contained only cheaper metals, and so their smooth edges were allowed to remain.
