Identify as many currencies as you can in this picture. What might the different currencies tell you about the cultures that created them? Since the paper money has little inherent worth, what gives the money value?
Why do we have pennies? Were they created in a day when items or services could be purchased for such a low price? Do we still need them? In a time when people drop pennies and don't take the time to pick them up, or when you can enter a local convenient store and see a dish of pennies people left because they don't really want to carry them in their pocket, do you ever wonder why we still have them, do they serve the same purpose as they did years ago? Does it cost more to make the penny than it is worth? How might it change our economy if we stopped making and using pennies? Does it make you think?
