stop making pennies

I think pennies shouldn't be made anymore. The making of pennies was changed because it cost more to make them than they were worth, which is only one cent. Most people throw them or just lose them, they are senseless. They are almost worthless, and take too much time to make, if they were cut out, the price of copper would likely go up, which would boost the economy, it would be much easier for everyone if we didn't have pennies, everything could be rounded up or down to the nearest nickel for prices.
