Reorganization of Indonesian states and east indies

Hello @Reslumi here is a plan to solve the mixed years and issuers in Indonesian states.

1) move the folowing under indonesien republic

• Riau
• Irian Jaya

2) can the European issuers of java just be added to the larger periods for the east indies 

i.e. appropriate coins of  Java be merged into United East India Company (1602-1800) and so on

As long as they stay independent issuers, Riau and Irian Jaya being under Indonesia makes sense.

As for Java, I agree that the colonial issues should separated from the native coinage like the massa. Dutch Javanese coinage should be under Dutch East Indies for example. The “Java” issuer should be exclusively native coinage, in my opinion.
