They get caught in you vacuum cleaner. Pennies suck! They are nothing but an everyday nuisance that needs to go! They are worth more per pound as raw copper then they are as legal tender.
Pennies may be legal tender but try unloading them to anyone including your own bank. Nobody wants them. Since the politicians won’t get rid of them, it’s time to melt them down. Businesses simply need to round off sales to the nearest nickel. In the long run it will save on labor costs.
