The genuineness of a coin can be known after verification of its metal composition

This was stated by Minister of State in the Ministry of Finance in written reply to a question in Lok Sabha today.

Counterfeit coin circulation requires verification of metal composition under coin standards; criminal investigation and seizures follow. Police discovered manufacturing facilities producing counterfeit coins, recovered counterfeit pieces of multiple denominations, and registered criminal cases. The Government relies on a Gazette notification prescribing the standard weight and remedial tolerances for the bi-metallic ten-rupee coin. Determination of genuineness requires verification of a coin's metal composition, which is the operative forensic criterion used alongside criminal investigation and seizures.
