The main Roman currency during most of the Roman Republic and the western half of the Roman Empire consisted of coins including: the aureus (gold), the denarius (silver), the sestertius (bronze), the dupondius (bronze), and the as (copper).These were used from the middle of the second century BC until the middle of the third century, a remarkably long time. They were still accepted as payment in Greek influenced territories, even though these regions issued their own base coinage. Either called Greek Imperial or Roman provincial coins.

During the third century, the denarius was replaced by the double denarius, now usually known as the antoninianus or radiate, which was then itself replaced during the monetary reform of Diocletian which created denominations such as the argenteus (silver) and the follis (silvered bronze). After the reforms Roman coinage consisted mainly of the gold solidus and small bronze denominations. This trend continued to the end of the Empire in the West.

The United States one-cent coin, commonly called a penny, is a unit of currency equaling ¹⁄₁₀₀ of a United States dollar. Its obverse has featured the profile of President Abraham Lincoln since 1909. Since 1959, the reverse has featured the Lincoln Memorial.

The coin has gone through several designs over its two-hundred year history. Until 1857 it was about the size of the current half-dollar coin. In 2009 the cent will get a one-year, four-coin commemorative program marking the 100th anniversary of Lincoln being placed on the cent.
