What will I do? Half my savings are in pennies! I carefully hoard the things until I have about twenty bucks worth, then cash them in at the bank, because that's the only place that will take the things. They're perfect for savings, as they are completely unusable money.
But more than this, think of what the loss will mean for the English language. When I give my grandchildren a piece of my hard earned wisdom through cliches such as: "A penny saved is a penny earned", they will just stare at me blankly. I will be even more out of touch than ever before. The term "penny pincher" will likewise be meaningless, and "nickel pincher" just doesn't have the same ring to it.
