How large is the coin collecting hobby in the United States?
There are millions of coin collectors in the U.S. today, and the number continues to grow. According to the United States Mint, over 100 million new collectors entered the hobby starting in 1999 due to the introduction of the Mint’s State Quarters Program. Many of those who started out collecting only state quarters became exposed to the wide variety of classic, seldom-seen U.S. coins and expanded their collecting interests into other areas of U.S. numismatics. Because the supply of rare, classic coins is limited, they have become much more elusive and desirable as time passes and the number of collectors grows.
