Indonesian rupiah coinage was first issued in 1951 and 1952, a year or so later than the first Indonesian rupiah banknotes printed following the peace treaty with The Netherlands, agreed in November 1949. Although revolutionary currency had been issued in by the provisional Republic of Indonesia between the declaration of independent on 17 August 1945 and 1949, it had all been formed of paper, metal being far too scarce for the internationally isolated government to use as currency.
Due to high inflation in the late 1950s and early 1960s, no coins were minted after 1961, and that which remainied in circulation was effectively worthless.
A devalued 'new rupiah' was issued in an attempt to tame inflation in 1965, with banknotes in denominations all the way from 1 sen (1 cent) up to 100 rupiah - no coins were struck at this time. By 1971, however, the economy, and inflation, under Suharto's New Order was stable, and coinage was once again issued, in denominations of 1, 5, 10, 25 and 50 rupiah, with 100 rupiah added two years later. Due to inflation, the current coinage now consists of 25, 50, 100, 200, 500 and 1000 rupiah, although older 1 rupiah coins remain officially legal tender for completeness.
Unlike coinage of the Netherlands Indian gulden (which in higher denominations were made of silver or gold), circulating rupiah coinage has always been formed of base metal.

For the first couple of years until sufficient coins had been issued, government sen notes were circulated, of 10, 25 and 50 sen denominations. No lower denominations were printed, but the old bronze Netherlands Indies gulden coins of 1/2, 1 and 2½ sen remained as legal tender (higher denominations, starting from 1/20 gulden (5 sen) had been silver, with greater intrinsic metal value).
Coinage, issued in 1951 and 1952 and from then until 1961, replaced the notes as sufficient coinage entered circulation. Under Indonesian law originally enacted by the Dutch, issue of money below 5 rupiah (in Dutch times gulden), was the responsibility of the government, and hence all coins bore the name of Indonesia, rather than the central bank.
The denominations were 1, 5, 10, 25 and 50 sen. The 1 and 5 sen coins had centre holes, similar to the old copper coins of the Dutch, while the other coins were solid. All were aluminium except the 50 sen, which was copper-nickel. 1 sen coins were effectively worthless, and only a token number of 100,000 were minted, all dated 1952. 5 sen coins were more useful and were also minted dated 1954, as was the 10 sen.
From 1954, Indonesia began to eliminate use of Malay Arabic script (Jawi), which had been a feature of the coins of the Netherlands Indies as well as of past Islamic sultanates in the archipelago. The 50 sen coin was the first to be changed, with the Arabic text simply removed from the coin for its 1954-dated minting.
The 25 sen was the next to have the Arabic removed, with "INDONESIA" replacing its Jawi equivalent for the second minting of the coin, dated 1955 (the 50 sen was also minted that year).
Inflation meant that the smallest denomination to be minted after 1954 was the 10 sen, which likewise had Arabic removed from its reverse for its third minting, 1957; 25 and 50 sen coins were also minted in 1957.
After 1957, the cupro-nickel 50 sen was debased to aluminium, the same metal as the lower denomination coins (which were never minted again). As a result of this, the 50 sen, previously the heaviest, but second-smallest coin - slightly larger than the 1 sen, was now the largest coin in circulation (albeit lighter than its predecessor).

A variation of the 1952 50 sen coin was issued in gold with an official value of 25 rupiah (although no value on the coin). The coin varied from the 50-sen by featuring the logo "BEKERDJA-MENABUNG-MEMBANGUN" and the Garuda emblem instead of the year and denomination. Like the other 1951–1952 coins, this one has the mintmark of Utrecht.
With the raging inflation of the 1960s very much under control at this point, coin issuing resumed after a 10 year hiatus, and coins were issued on January 1, 1971, of denominations 1, 2 and 5 rupiah, all in aluminium. 10, 25, and 50 rupiah coins were added, in cupro-nickel, on 5 April 1971. The coins featured on the obverse 'Bank Indonesia' a large '1' with 'rupiah' underneath and the year '1970' (1, 2, and 5 rupiah) or '1971' (10, 25, 50 rupiah).
The reverse of the coins showed "Rp 1", "Rp 5", "Rp 10", "Rp 25", "Rp 50", plus various designs: White-browed Fantail (1rp), rice and cotton stalk (2rp), Black Drongo bird (5rp), rice and cotton stalk with Indonesian wording "TINGKATKAN PRODUKSI SANDANG PANGAN" ("increase the product of clothing and food") (10rp), Victoria Crowned Pigeon (25rp), and Greater Bird of Paradise (50rp). The final mintages of these coins were: 136 million (1 rupiah), 139 million (2 rupiah), 448 million (5 rupiah), 286 million (10 rupiah), 1.22 billion (25 rupiah) and 1 billion (50 rupiah).
The 10 rupiah coin was issued as part of the UN Food and Agriculture Organization coins and medals program,[1] an international issue by ultimately 114 countries. A variety of coin sets were sold to coin collectors in order to raise money for the UN's food program. In addition to the sale to collectors, the vast majority of the 10 rupiah coins were used within Indonesia - in addition to some rarer coins (none of which were issued in Indonesia) the FAO wanted low denomination circulating coinage that called for increasing food production.
At the time the exchange rate was 378 rupiah to the US$, so the smallest coin was worth approximately 1/4 of a US cent (note however that the 1 and 2 rupiah coins were never reissued, and hence the 5 rupiah coin was shortly to become the smallest denomination).
The coin selection was extended with a '1973'-dated cupro-nickel 100 rupiah coin of large size showing a Minangkabau tribal house, which was issued on 2 January 1974, at which time the coin was worth about US$0.24. A total of 913 million of these coins were minted, some of which are still found in circulation today.
As a result of the successful reestablishment of coinage in Indonesia, notes below 100 rupiah were withdrawn in Indonesia permanently from September 1, 1975 (at which point the exchange rate was fixed at 415 rupiah to the dollar, hence the largest denomination banknote to be withdrawn, the 50 rupiah note, was worth around US$0.10).
The 5 rupiah aluminium coin was revised dated 1974, the obverse changing only the date, but the reverse depicting the logo of KB ('Keluarga Berencana', aka family planning', a movement first established by the Indonesian government in 1970), i.e. a 2-parent, 2-child family with rice and cotton stalk and letters KB, with the text 'KELUARGA BERENCANA' ('family planning') 'MENUJU KESEJAHTERAAN RAKYAT' ('for the welfare of the people'). 448 million were minted.
The 10 rupiah was enlarged substantially dated 1974, with the composition changed to brass-clad steel, with the obverse unchanged, and the reverse changed to show the symbol of Tabanas, the government's 1970-established national savings scheme, and the slogan 'MENABUNG UNTUK MENUNJUNGAN PEMBANGUNAN' ('save to support development') 223 million were minted.
Both of these coins were also sold to collectors as part of UN FAO sets.
The 1973 100 rupiah was given an updated reverse design in 1978, reading 'FOREST FOR WELFARE' '1978' and a forest motif. The coin was also made thinner, although its dimensions did not change. This was the fourth and final Indonesian FAO coin.
The 1974 5 rupiah, meanwhile, was updated '1979', issued from March 1980, retaining its family planning message, but adding a circular decoration to both reverse and obverse of the coin, and being shrunk in size from 3.0 to 1.4 grams, presumably to cut the cost of production. 413 million coins were minted dated 1978, while 5 million were later issued dated 1995 and 1996.
The 1974 10 rupiah was similarly updated with decoration to '1979', enlarged with the composition changed to aluminium. 286 million were minted with this date. No 10 rupiah coins have since been issued.
From 1979, no new coin designs were made in Indonesia until 1991. For new coinage, the old style of a large number was replaced instead with the national Garuda Pancasila logo, with the year and "BANK INDONESIA" in smaller text below the emblem.
A 25 rupiah coin dated 1991 in aluminium, with images of nutmeg and its Indonesian text 'buah pala' and "Rp 25" on the reverse, was the smallest coin to be revised. The same coin was also minted 1992–1996, with mintages each year of 30, 64, 20, 250, 185, and 5 million. No 25 rupiah coins have been issued since 1996.
50 rupiah (backed with a komodo dragon and text 'komodo' was issued in aluminium-bronze, dated 1991, and later 1992, 1993, 1994, 1995, 1996, 1997 and 1998. Mintages were 67, 120, 300, then 590 million, then 150,000 each year.
The 100 rupiah, also aluminium-bronze was inscribed with an octagon, featuring the reverse design of running bulls with the text 'karapan sapi' (bull running). The coin was minted 1991 through 1998, with respective mintages of 94, 120, 300, 550, 799, 41, 150, and 56 million.
A 500 rupiah coin, also in aluminium-bronze, became the first new coin denomination since 1973, with a value at issue of around US$0.20. The coin depicted on its reverse the jasmine flower with the text "bunga melati". This coin was minted dated 1991 and 1992, with mintages of 71 million then 100 million.
1993 extended the range of coin denominations, adding 1000 rupiah, then worth around US$0.40 a bimetallic coin of copper-nickel and aluminium-bronze. This coin depicts an oil palm 'kelapa sawit', and was minted 1993, 1994, 1995, 1996, 1997 and 2000.
The 500 rupiah coin was updated '1997' with a smaller jasmine leaf above a large central '500' with smaller lower 'rupiah', and the same aluminium-bronze material. The coin was minted dated 1997, 2000, 2001, 2002 and 2003.
The next coin design, was '1999' 50 rupiah coin , which was struck in aluminium showing the Black-naped Oriole. As with the 500 rupiah, the reverse of the coin has a larger numerical denomination. Dates are 1999, 2001, 2002, and 2003.
The 100 rupiah coin was also altered in the same manner to aluminium from '1999', depicting the palm cockatoo. Mint dates are each year from 1999 through 2005.
The last coin revisions in Indonesia are of 2003.
The 200 rupiah coin in aluminium, depicting the Bali Starling 'jalak bali' was introduced as a new denomination in the same style as the 50 and 100 rupiah coins, dated '2003', while the jasmine 500 rupiah coin was again redesigned, with its metal changed to aluminium and its size enlarged.
There are presently two series of coins in circulation: aluminium bronze and bi-metallic coins from 1991–1998 and light-weight aluminium coins from 1999 onwards. Due to the low value and general shortage of small denomination coins (below 100 rupiah), it is common to receive sweets in lieu of the last few rupiah of change in supermarkets and stores. The 1 rupiah coin is officially legal tender for completeness' sake, but is not circulated as it is effectively worthless.

Although circulating coins in Indonesia have never been made from precious metals, a number of special issues have been made since coins were reintroduced to Indonesia in 1970 from either silver or gold. As commemorative coins, they were all sold above their intrinsic value, and also above their nominal value.
All the coins struck are proof coinage, with the exception of the WWF 1974 coinage which were issued in non-proof 50% silver, and proof and non-proof gold.
36,000 gold pieces of the 1952 50 sen were minted that year, with the obverse design replaced with the Garuda Pancasila and text "INDONESIA" "BERKERDJA MENABUNG MEMBANGUN".
With the exception of the WWF and Save the Children issues, which are in good supply, most of the coins are relatively scarce and command good premiums to their bullion value.
