The United States monetary system, overseen by the Federal Reserve, features a complex array of coins, each with distinct designs and denominations that serve both economic and cultural purposes. All U.S. coins bear the inscriptions "IN GOD WE TRUST" and "E PLURIBUS UNUM," with 100 cents equaling one dollar.

Penny (1¢)

The one-cent coin , made of copper-plated zinc, features Abraham Lincoln, the 16th U.S. president, on its obverse. The reverse displays the Lincoln Memorial, honoring his legacy.

Nickel (5¢)

Slightly larger than the penny, the five-cent coin is crafted from nickel-copper alloy. It bears the likeness of Thomas Jefferson, the third U.S. president, with his historic home, Monticello, depicted on the reverse.

Dime (10¢)

Despite being smaller than the nickel, the ten-cent coin is made of the same nickel-copper blend. It honors Franklin D. Roosevelt on the obverse, while the reverse features a torch symbolizing liberty and enlightenment.

Quarter (25¢)

The quarter-dollar coin , composed of cupronickel, is one of the most commonly used denominations. George Washington appears on the obverse, while the reverse alternates between the Great Seal of the United States and designs representing each state. Its widespread use in vending machines, parking meters, and laundry facilities makes it particularly practical.

Half Dollar (50¢)

The less frequently encountered half-dollar coin is larger and heavier than other denominations. It features John F. Kennedy on the obverse and the Presidential Seal on the reverse.

Dollar Coin ($1)

The golden one-dollar coin , made from manganese brass alloy, celebrates Sacagawea, the Native American guide of the Lewis and Clark expedition. The reverse depicts a bald eagle, emblematic of American freedom.

These coins not only facilitate daily transactions but also serve as miniature canvases that reflect America's rich historical narrative and cultural values.
