Coins can be exchanged at any branch of banks namely HDFC Bank, Standard Chartered Bank, Prathma Bank, Axis Bank, Nanital Bank and ICICI Bank, said assistant general manager of RBI, JP Singh.

"The coins will be exchanged at the branches of these banks/offices of the Reserve Bank till the close of business on June 29, 2011," he added.
