In a post that appeared early in 2014 on the site, a very interesting and mathematically elegant question was posed which we study here. Consider the US coinage system (coins only; we do not include any notes of value $1 or more). We have the following coins: Penny (1 cent, $ 0.01), Nickel (5 cents, $ 0.05), Dime (10 cents, $ 0.10) and Quarter (25 cents, $ 0.25). Each of these coins is made of some metal or mixture of metals, and as such each one has a cost associated with it. After all, the metals in question have to be purchased from the market!
