Elimination of Pennies

If you saw a penny lying on a sidewalk, would you pick it up? I wouldn't. If I saw a nickel lying on a clean sidewalk, I would probably stoop to pick it up. The point is: a penny is worthless. It won't buy anything anymore. Pennies are a nuisance and help clog your pocket and purse. I have tried for several years to get our members of Congress to enact legislation abolishing the pennies. But no luck. Fairly recently I heard of a congressman from Arizona that introduced such legislation. I contacted him. He said there was too much opposition to his bill from business interests because of the great cost and trouble in making the change.
Nevertheless, I think pennies should be eliminated. By the time this could be accomplished, the nickels would also be worthless. So let's include nickels in the crusade.
