Know the Mintmarks on Coins of India

Every coin minted in India bears a mint mark, a unique symbol that identifies the mint where it was produced. Mint marks primarily serve the purpose of traceability, enabling the issuing authority to identify the origin of each coin. India currently has four Government Mints, some of which trace their origins to the pre-Independence era.

The newest of these is the Noida Mint, established in 1988. In the past, India occasionally faced shortages of circulation coins and relied on foreign mints to supplement domestic production. Today, however, the country has sufficient—and often surplus—minting capacity to meet its own coinage requirements through its four Government Mints. In addition to producing India's circulation and commemorative coins, the Noida Mint has also undertaken the minting of coins for several foreign countries.

The Myth of India's 2019 "Raindrop Series" Coins

Image
Among Indian coin collectors, the 2019 definitive coin series is widely referred to as the "Raindrop Series" or "Raindrop Coins."  The nickname has become so common that it frequently appears in coin trading groups, online marketplaces, catalogues, and social media discussions. However, despite its popularity, the term is technically incorrect and finds no support in any official Government document. The coins were never intended to depict raindrops; rather, they were designed to showcase India's agricultural strength through the depiction of grains. The 2019 definitive series marked one of the most significant redesigns of India's circulating coinage in recent years, comprising the ₹1, ₹2, ₹5, ₹10, and ₹20 denominations. Besides introducing the country's first circulating dodecagonal bi-metallic ₹20 coin, the series was designed to be more accessible to visually impaired individuals through distinct sizes, weights, and edge patterns, making each denom...
