So you made me curious about the quarters. I had a few of each in my desk top stash. The 022’s measure about 0.069 “ thick. The 023’s here measure more like 0.064/0.065” depending on just where you grab them. But they all, including olders, weigh 5 grams. So at least Bidum figgered out a way to put cheaper, denser stuff in the new ones?
Coin operated machines, I suspect; like the showers in the harbor. $.25 a minute.
