> But, if we stopped minting pennies because they cost too much (3.7 cents), it's hard to imagine we're going to keep producing nickels when they cost 13.8 cents to mint. Dimes are much cheaper than nickels (5.8 cents), and quarters aren't too bad relative to face value (14.7 cents).

Coins aren’t disposable. Why does it matter if the production cost is higher than the face value?
