Collectible coins are numismatic items sought after by collectors and investors due to their historical significance, rarity, or unique characteristics. In the United States, coins like the twenty-five cents quarter, often referred to simply as "quarters," come in various designs, many of which commemorate historical events or figures. The Sacagawea dollar, introduced in 2000, features the image of Native American woman Sacagawea and is notable for its golden color and smooth edge. Both types of coins can hold considerable value beyond their face value depending on factors like condition, demand, and historical context.
