Banknotes of Indonesian Rupiah
Here are two current issues of Indonesian banknotes the 2000-2001 notes of 1000 and 5000 rupiah, and the the 2004, 2005 notes of higher denominations (10000, 20000, 50000 and 100000 rupiah), with better anti-forgery devices. The 1998-1999 notes have no longer been legal tender since 31 January 2008 (but will be exchangeable until 31 January 2018 at Bank Indonesia). Earlier notes are also no longer legal tender, due to the lack of security features and association with the Suharto regime, but can be exchanged in Bank Indonesia offices until 2010.
As the smallest current note is worth approximately US$0.10, even small transactions such as bus fares are typically conducted with notes, and the 1,000 rupiah note is far more common than the 1,000 rupiah coin. The government initially announced that this would change, with a 2000 rupiah note to replace the 1000 rupiah, with that denomination replaced by a coin. After a long delay, this proposal was revised so that the 2000 rupiah banknotes was launched by BI (Bank Indonesia) on 9 July 2009, with the banknotes circulating as legal tender from 10th July 2009, but without withdrawing the 1000 rupiah note.
Due to the low value of the (older series) notes below 1000 rupiah, although they are no longer being circulated, some remain in use in increasingly poor condition, as low denomination 'uang pasar' (literally market money), outside the banking system for use in informal transactions.
