Should we abolish pennies?

As the economy has grown over the years and prices have risen, the value of pennies has decreased significantly. In the late 1800s and early 1900s, pennies were an essential component to the economy. They held more value, and people frequently used pennies as items did not cost as much. However, over the years, pennies have lost their value as inflation has occurred and the economy has soared.  Pennies are generally discarded on sidewalks, and left untouched by passing people. In addition to this, few people use pennies when making purchases. Instead they'll pay with checks and credit cards, because it is quicker and more efficient. If the government were to abolish pennies, it would probably even benefit the economy because the government would save money by not producing them.
