Indonesian rupiah coinage was first issued in 1951 and 1952 . The rupiah became Indonesia’s official currency in 1949, when it replaced the Indonesian Dutch East Indies guilder. Because the currency depreciated greatly during the 1950s, a new rupiah was issued in 1965; the rate of exchange was 1,000 old rupiah for 1 new rupiah.. coin issuing resumed after a 10-year hiatus, and coins were issued on 1 January 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) . 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. Today, we have coins of 50, 100, 200, 500 and 1000 rupiahs.
