The two-dollar bill is a denomination of United States currency that features a portrait of Thomas Jefferson, the third President of the United States, on the front. It was first issued in 1862 and is known for its distinctive green color and unique design, which includes an image of the Signing of the Declaration of Independence on the reverse side. Although it is still legal tender, the two-dollar bill is relatively rare in circulation compared to other denominations. Many people consider it a collector's item, and it is often given as a novelty gift or used in special occasions, making it a symbol of good luck in some cultures.
