Community currencies seem to be on the upsurge as small towns and large cities recognize the value of supporting their local economies. There are numerous models including: BerkShares, Local Exchange Trading Systems (LETS), and hours currency.
Local currencies are spreading as more communities see the value of supporting their local economies. Some of the more well-known local currencies in the U.S. include: the BerkShares, in the Berkshire county of western Massachusetts, the Ithaca Hours in Ithaca, New York and the Plenty in North Carolina. In Europe, micro currencies are taking off in Germany and the concept perhaps will spread to Asia and Latin America.
