NEW YORK (CNNMoney) -- It may seem like Monopoly money to outsiders, but a growing number of communities across the U.S. are using homegrown local currencies to stimulate their economies and protect themselves from the nation's broader economic woes.
While there were only about 20 active community currencies in the United States in 2009, there has been a recent resurgence, with at least a dozen communities developing their own currencies in the past couple of years, estimates Loren Gatch, a professor of political science at the University of Central Oklahoma who researches these alternative currencies. In addition, currencies that have been around for years have seen a spike in interest, with membership doubling in some cases.
