1. Each year the U.S. mint melts down old coins that are worn or damaged. They also produce new coins to replace those removed from circulation. Also, a small percentage of coins are lost or destroyed each year, and no longer in circulation. The result is that the 2004 coin year is the most common in circulation with fewer and fewer coins from each previous year.
