The Indian Rupee is the currency used in Tamil Nadu as well as throughout other parts of India. Controlled by the Reserve Bank of India, the Indian Rupee is made up 100 paise which is singularly known as paisa.
Historically, the rupee, derived from the Sanskrit word raupya, which means silver, was a silver coin. This had severe consequences in the nineteenth century, when the strongest economies in the world were on the gold standard. The discovery of vast quantities of silver in the U.S. and various European colonies resulted in a decline in the relative value of silver to gold. Suddenly the standard currency of India could not buy as much from the outside world. This event was known as “the fall of the rupee.”
