Specifically for cents, why does the mint need to make billions of coins every year? Where do they all go? Even zincoins lasts more than a year. Is there really a demand (and from who) for that much? ~26billion cents in the last 3 years, why? If there's an old thread for this, please link me. I'm asking because I want copper back in Lincoln cents and was thinking maybe the mint can make just 1/2 of their normal year mintage and use the money to make copper cents instead of zinc. I read somewhere money is the reason they switched to zinc, cheaper to make zincoins.
