When is a Penny Not a Penny?
From 1902 to 1958 the US penny contained 95% copper. Today a penny contains 2.5% copper. So the next time you go to the bank ask the teller to cash your check in wheat pennies. Unfortunately, paper currencies are headed for like vaporization. Or, one could make the case inflation has already bankrupted the US dollar. Local farming is headed for a boon in the next few years or decades.
