Most excellent point. I was scratching my head while reading the article.
But...that stated: I’m one of the few who still uses cash.
I know from experience that you never know what you’ll be handed in change. It’s a good reminder that it’s worth a look before dropping change in a meter (as I did yesterday, without looking).
30 or 40 years ago it was a not so deep secret that you could buy rolls of quarters and half dollars at the bank, break them open at home, and there was a good chance you’d find plenty of silver coins. Be it 90% or 40%. Theoretically that could probably still happen but it’s not worth the trouble anymore. There just aren’t enough of them.
