Since the American Eagle Gold and Silver Act was signed by President Ronald Reagan in $1985,$ the U$.$ S$.$ Mint has produced millions of American eagle gold and silver coins. These are legal tender coins with a face value of $$50$ for the American eagle gold coins and $$1$ for the American eagle silver dollars. Thus, the US government issues two legal tender currencies: paper dollars with a face value of $$1,$ and silver eagles with a face value of $$1.$ Last year over $50$ million eagle silver dollars were minted, but none of them circulate and few Americans, including top government officials, have even seen these coins or held them in their hands; rather, all are stored away in safes around the world. Demonstrate why this is an example of Gresham$$s law: $$Bad money drives out good.$$ Which is the $$bad$$ money and which is the $$good$$ money?
