Today, a cup of coffee is around $2 a cup or 20 silver dimes. That’s 20 times more than the late 1960s when a cup of coffee around here cost .10 Cents each or ONE Silver Dime.
There are 715 pure ounces of Silver in $1,000 face value. So 20 times face value, on a ten cent silver dime. Silver today would have to be $28/per ounce to be equal to the old .10 cent cup of coffee.
Double check my math.
