BerkShares is a local currency that circulates in The Berkshires region of Massachusetts. It was launched on September 29, 2006 by BerkShares Inc., with research and development assistance from the New Economics Institute. The BerkShares website lists over 370 businesses in Berkshire County that accept the currency. In 30 months, 2.2 million BerkShares have been issued from 12 branch offices of five local banks. The bills were designed by John Isaacs and are printed by Excelsior Printing on special paper with incorporated security features from Crane & Co.. BerkShares are pegged with an exchange rate to the US dollar, but Nick Kacher of the New Economics Institute has discussed the possibility of pegging its value to a basket of local goods in order to insulate the local economy against volatility in the US economy.
