The Reserve Bank of India puts into circulation coins minted by the Government of India. These coins have distinctive features. Coins in new denominations to meet transaction needs of public and coins in new designs to reflect various themes - economic, social and cultural - are introduced from time to time.
As coins remain in circulation for longer periods, it is quite possible that coins of different designs and even shapes are circulating at the same time. One such change is introduction of 'Rupee symbol' in coins in July 2011.
An instance of this is the Rs. 10 coins with rupee symbol and the same denomination coin without rupee symbol. Both of them are legal tender and equally good for transactions, though they may look a little different.
It has been reported that some less-informed or uninformed persons who suspect the genuineness of such coins are creating doubts in the minds of ordinary people including traders, shop-keepers, etc., impeding the circulation of these coins in certain pockets of the country causing avoidable confusion.
The Reserve Bank has advised members of the public not to give credence to such ill-informed notions and ignore them and continue to accept these coins as legal tender in all their transactions without any hesitation.
