India Government Mint located at Mumbai (commonly known as Mumbai Mint) is selling Commemorative coin sets over the counter from January 02, 2012 at their newly inaugurated counter. The counter will be open on all working days between 10AM and 12PM.
Payment can be made either by a Demand Draft or credit/debit cards. Each person is allowed to purchase one set per variety of any theme. It is not known which sets are available for purchase through the counter. However it is highly unlikely that these will include old sets. Most probably only the recently minted coin sets may be available for sale. If anyone visits Mumbai mint for purchasing these coin sets over the counter, please do send us your feedback.
