So get rid of them. At one point in my life, a long time ago, things could be purchased for a penny. That time has long passed. Now pennies are used just to make the math work out. Round everything up a nickel ($0.05) and call it a day. Or look at it another way: inflation has made the nickel from my youth into today's penny.
The same argument could be made for the nickel and the dime. (How many of us collect them in a jar, and pay a 10% royalty to turn them into dollars?)
We all know that the real reason we hold on is that we know the price of everything will go up. Skinflints!
