It was later clarified by the Reserve Bank of India (RBI) that the “alleged fake” coin was the earlier 2008 design, which predated the adoption of the ‘₹’ symbol in 2010, and was still in legal circulation, along with the 2011 design and those refusing to accept it could face legal action.   
The Indian 10-rupee coin ( ₹ 10) is a denomination of the Indian rupee. The ₹10 coin is the highest-denomination coin minted in India since its introduction in 2005. The present ₹10 coin in circulation is from the 2019 design. However, the previous ₹10 coins minted before 2019 are also legal tender in India. All ₹10 coins containing with and without the rupee currency sign are legal tender, as stated by the Reserve Bank of India. Along with the standard designs, there are 21 different designs for this denomination and are minted as circulating commemorative coins, this is used alongside the 10 rupee banknote.
Not only the Rs 10 coin faced rejection in circulation but also the newly minted Rs 1 coin is facing unauthorized demonetization in some parts of the country as well. For rupee ten coin, RBI previously issued notice for it being the valid currency and warned people about facing legal action for rejecting such coins.
While states like Uttar Pradesh have such immense number of coins in the circulation that every month or two, there surfaces a rumour which tends to cut them off the circulation, other states face a shortage of the coins. However, in recent times, the shortage in other areas has improved.
