So far, I've only seen my mother with this kind of exaggerated amount of coins. I've recently seen people on websites interested in buying coins from 40 years ago by the kilo. The last time I checked, they were offering between $3 and $5 per kilo for coins from 1975 or older. My mother was even tempted to sell her coins at the height of the crisis; I don't know how much they offered her.
