Citeer: "ceh2019"We also need to sort out which notes were issued before and after the currency reform of 1965. My understanding is that the new notes introduced were those dated 1963 and 1964 (P#80 - P#81 and P#89 - P#101) but finding confirmation of this is hard. Currently, all these notes are placed in the earlier rupiah, with the first notes of the later rupiah being those dated 1968. This can't be right but some clear, authoratative statements would be very helpful.
Ok let me answer this part first.
The notes from P#80 - P#81 and P#90 - P#101 are indeed the ones issued as part of 1965 currency reform. Here is an excerpt from a document from Bank Indonesia which can confirm that, and you can check it at page 2 of this document:

Sebagai persiapan terwujudnya kesatuan moneter bagi seluruh wilayah Republik Indonesia, dikeluarkan Penetapan Presiden (Penpres) No. 27/1965 tanggal 13 Desember 1965. Penpres ini menetapkan pengeluaran uang rupiah baru sebagai alat pembayaran yang sah di seluruh wilayah Republik Indonesia. Penetapan ini telah memberikan wewenang penuh kepada BI untuk mengeluarkan semua jenis uang dalam berbagai pecahan. Hal ini merupakan penyimpangan dari UU No. 11/1953. Uang baru tersebut mempunyai nilai Rp 1 (baru) = Rp 1.000 (lama) dan Rp 1 (baru) = IB Rp 1.
(As a preparation for the realization of monetary unity for all parts of the Republic of Indonesia, a presidential decree (Penpres) No.27/1965 dated 13 December 1965 was issued. The decree stipulates a new Rupiah as a legal tender in all parts of the Republic of Indonesia. This decree gave full authority for BI to issue all kinds of currency in various denominations. This was a violation of Law No.11/1953. The new currency has the rate of
Rp 1 (new) = Rp 1000 (old) and Rp 1 (new) = IB Rp1)
*IB Rp refers to local issue of Rupiah that is only valid in Papua/Irian Jaya
*Law No.11/1953 allows Bank Indonesia to only issue notes from Rp 5 and above
Berkaitan dengan penetapan itu, BI mengeluarkan uang kertas Seri Dwikora bertanda tahun 1964 dalam pecahan 1 sen, 5 sen, 10 sen, 25 sen, dan 50 sen; uang kertas Seri Presiden Soekarno bertanda tahun 1960 dalam pecahan Rp 5, Rp 10, Rp 25, Rp 50, Rp 100, Rp 500, dan Rp 1.000; uang kertas Seri Presiden Soekarno bertanda tahun 1964 dalam pecahan Rp 1 dan Rp 2.50.
(In accordance to that decree, BI issued Dwikora series banknote with year 1964 in 1 sen, 5 sen, 10 sen, 25 sen, and 50 sen denominations; Soekarno series banknotes with year 1960 in Rp 5, Rp 10, Rp 25, Rp 50, Rp 100, Rp 500, and Rp 1.000 denominations; Soekarno series banknotes with year 1964 in Rp 1 and Rp 2.50 denominations).
And from that document we can see that the new banknote of 1965 reform are:
Dwikora series are P#90-P#94
Soekarno series 1960 are P#82-P#88
Soekarno series 1964 are P#80 and P#81
No information about P#89
