New coins have been produced annually since then and they make up a valuable aspect of the Indian currency system. Today, circulating coins exist in denominations of 50 p ( i.e. 50 paisa or ₹ 0.50 ), ₹ 1, ₹ 2, ₹ 5, and ₹ 10. All of these are produced by four mints located across India, in Kolkata, Mumbai, Hyderabad and Noida.

The first rupee coins of the Republic of India were minted in 1950. These included 1 / 2 rupee, 1 / 4 rupee, 2 anna, 1 anna, 1 / 2 anna & 1 pice coins, and are referred to as the anna series or pre-decimal coinage. Under the anna series, one rupee was divided into 16 annas or 64 pice, with each anna equal to 4 pice. In 1957, India shifted to the decimal system, though for a short period of time, both decimal and non-decimal coins were in circulation. To distinguish between the two pice coins in circulation, the coins minted between 1957 and 1964 were printed with the legend `` Naya Paisa '' ( `` New Paisa '' ). The denominations in circulation were 1, 2, 3, 5, 10, 20, 25, 50 ( naya ) paisa and one rupee. Since rupees retained their pre-decimal value, pre-decimal coins of one, half and quarter rupees remained in circulation after decimalisation. The word `` naya '' was dropped in 1964 and a new denomination, the 3 paisa, was introduced into circulation. A 20 paisa coin was minted in 1968. Neither of these coins gained much popularity. The 1, 2 and 3 paisa coins were phased out gradually in the 1970s. In 1982, a new 2 rupee coin was introduced experimentally to replace 2 rupee notes. The 2 rupee coin was not minted again till 1990, after which it was minted every following year. Stainless steel coinage of 10, 25 and 50 paisa was introduced in 1988. In 1992, a new stainless steel rupee coin, smaller and lighter than the older rupee, was minted, alongside a 5 rupee Cupronickel coin. In 2005, the 10 rupee coin was minted for the first time. Higher denomination coins were introduced due to an increasing demand for change and the increasing cost of printing 2, 5 and 10 rupee banknotes. On 30 June 2011, all coins in denominations of 25 paisa and below were officially demonetised. Commemorative coins in circulation can be found in various denominations. They depict various special events or people, including Mahatma Gandhi, Jawaharlal Nehru, Indira Gandhi, B.R. Ambedkar, Rajiv Gandhi, Dnyaneshwar, the 1982 Asian Games, Sardar Vallabhbhai Patel, Subhas Chandra Bose, Sri Aurobindo, Chittaranjan Das, Chhatrapati Shivaji, the 2010 Commonwealth Games, Bhagat Singh and Rabindranath Tagore. Coin series : 1947 - 1950 ( pre-decimalization ) Union of India 1947 -- 1950 At Independence on 15 August 1947, India was partitioned into the new British Dominions of India and Pakistan. The new Dominion ( or Union ) of India retained the previous imperial currency with images of British monarchs. The basic unit of currency was the Indian rupee, which was itself divided into annas ( 16 annas to a rupee ) and pice ( the old spelling of paisa - 64 pice to a rupee ). The lowest - denomination Indian coins, the half - pice ( 128 to a rupee ) and the pie ( 192 to a rupee ) were officially demonetized in 1947 ; while both denominations had continued to circulate up to that time, new examples were not minted after 1942 as they were practically worthless ( India remained a member of the sterling area after independence and the rupee remained pegged to the pound sterling. Until 1966, the rupee was worth 1s. 6d, or 18 old British pence ; a half - pice was therefore worth 0.141 old pence and a pie 0.09 old pence. ) From 15 August 1947 until 26 January 1950, the Indian coinage structure was as follows : ( bold - denominations minted ) Rupee and its fractions Annas Pice Pies ( demonetized after 1947 ) Rupee 16 annas 64 pice 192 pies Half rupee 8 annas 32 pice 96 pies Quarter rupee 4 annas 16 pice 48 pies 1 / 8 rupee 2 annas 8 pice 24 pies 1 / 16 rupee 1 anna 4 pice 12 pies 1 / 32 rupee Half anna 2 pice 6 pies 1 / 64 rupee 1 / 4 anna 1 pice 3 pies This represented the currency arrangements during the transition period up to the establishment of the Indian Republic. The coins used after 1947 until the introduction of Republic of India - Pre decimalisation series were as follows : George VI series ( Independent India ) ( 1947 - 1950 ) Denomination Image Metal Shape Diameter Minted in Year Obverse Reverse One Rupee Nickel Circular 28 mm 1947 Half Rupee 24 mm 1946 - 1947 Quarter Rupee 19 mm 1946 - 1947 2 Annas Nickel - Brass Square 25.1 mm 1945 Copper - Nickel 22 mm 1946 - 1947 1 Anna Nickel - Brass 12 Scalloped 21 mm 1945 Copper - Nickel 21 mm 1946 - 1947 1 / 2 Anna Square 19.7 mm 1946 - 1947 1 Pice Bronze Circular with a hole 21.32 mm 1943 - 1947 Republic of India 1950 - 1957 On 26 January 1950, India became a sovereign republic. This series was introduced on 15 August 1950 and represented the first coinage of Republic India. The British King 's portrait was replaced by the Lion Capital of the Ashoka Pillar. A corn sheaf replaced the Tiger on the one rupee coin. In some ways this symbolised a shift in focus to progress and prosperity. Indian motifs were incorporated on other coins. The previous monetary system and the old units of currency were retained unchanged.

However, it was in September, 1955 that the Indian Coinage Act was amended for the country to adopt a metric system for coinage. The Act came into force with effect from 1 April 1957, after which anna and pice denominations were demonetised. The rupee remained unchanged in value and nomenclature. It, however, was now divided into 100 ' paisa ' instead of 16 annas or 64 pice. Effective from 30 June 2011, all coins in denominations of 25 paisa and below were officially demonetized.

Coin series 1957 - present ( decimal ) Naya paisa series 1957 -- 1963 The antiquated spelling of `` pice '' was modified to `` paisa '' in the singular and `` paise '' in the plural. For public recognition, the new decimal paisa was termed ' Naya Paisa ' ( New Paisa ) till 1 June 1964 when the term ' Naya ' was dropped. The coins of 50p, 25p, 10p, 5p, 2p, and 1p had a legend in Devanagari script explaining the value of coin in terms of fraction of a rupee.

Small denomination coins which were made of bronze, nickel - brass, cupro - nickel, and aluminium - bronze were gradually minted in aluminium. The first coin minted in such type was the 3 Paisa coin in 1964, which was a new denomination, and continued to be minted till 1971. One and Two paisa coins were changed to Aluminium and were minted without the Devanagari legend from 1965. 20 paisa coin was introduced in 1968, which continued to be minted till 1971.

The size and the design of 10 paisa, 50 paisa and 1 rupee was changed, though they continued to be minted in the same metal. Coins of 3p, 2p and 1p were discontinued but continued to be the legal tender.

The very considerable costs of managing note issues of Re 1, Rs 2, and Rs 5 led to the gradual coinage of these denominations. These coins continued to be minted till 2004, when the Unity in diversity series was launched. Cupro - Nickel coins are not minted anymore. Ferritic Stainless Steel coins of Two and Five Rupee denominations are currently in production. 2004 Unity in diversity series In 2004, RBI issued a series in denominations of 1 rupee, followed by 2 rupee and 10 rupee in 2005. These issues however came into circulation in 2006, and created a controversy over their design. 10 rupee coins were the first bimetallic coins issued in India, and because of the controversy and being minted in only one mint, most of the coinage never found its way into circulation. The ones which did were hoarded by Coin collectors and Coin hoarders. 2004 Unity in Diversity Series Denomination Image Metal Shape Diameter Minted in Year Obverse Reverse 10 rupee Bimetallic Copper Nickel Center in Aluminium Bronze ring Circular 27 mm 2005 - 2007 2 rupee Stainless Steel 26.75 mm 1 rupee 25 mm 2004 - 2006 2007 Hasta Mudra series in 2007 RBi issued a new series of Coins, The Hasta Mudra Series, in coins of denominations 50 p, 1 rupee and 2 rupee.

Controversies Controversy over 2006 two - rupee coin denier of Louis. The two - rupee coin issued from 2006 by the Reserve Bank, in stark contrast to the earlier coin, is rounded and simpler in design, without the map of India. The coin has already been criticized for being difficult to recognize by the visually impaired. Most controversially, it features an equal - armed cross with the beams divided into two rays and with dots between adjacent beams. According to RBI, this design represents `` four heads sharing a common body '' under a new `` unity in diversity '' theme. However, Hindu nationalists have charged that the symbol is a Christian cross resembling the symbol on the deniers issued by Louis the Pious. Bimetallic coin This section may require cleanup to meet Wikipedia 's quality standards. The specific problem is : Non-encyclopedic style Please help improve this section if you can. ( July 2013 ) India 's much awaited first ever bimetallic 10 rupee coin was released in 2005 under the theme `` Unity in Diversity ''. But, due to its controversial design resembling a cross, it was criticised and was not minted in large numbers. Another reason for its availability being scarce is that it was minted only in one ( Noida ) of four mints in India. Coin dealers and the public who got this coin hoarded it and it never came into circulation. It is available for sale on some auction websites, but the price of this coin is very high in comparison to its denomination due to the uncertain number of issued coins. Some coin sellers claim that this coin is a limited edition. However, official information is not yet available on the number of mintage. A press release from Reserve Bank of India mentioned that there will be two themes of 10 rupee coins : `` Unity in Diversity '' and `` Connectivity and Information technology ''. From 2008 coins based on the second theme, `` Connectivity and Information technology '', were also released. The coin depicts 15 rays above the numeric 10. It was again minted only by the Noida mint and was not easily available in circulation. From 2011, the same theme was continued with a slight design change showing 10 rays instead of the earlier 15 and the introduction of the new Re symbol. Now it is being minted in all four mints, which are Mumbai, Kolkata, Hyderabad, and Noida. Apart from these definitive coins, 10 rupee bi-metallic commemorative coins have also been released as follows : 2008 -- Tri Centenary of Gur - ta - Gaddi 2009 -- Homi Bhabha Birth Centenary 2010 -- RBI Platinum Jubilee 2012 -- 60 Years of Parliament 's first sitting.
