For some Indonesian, wedding certainly need a well preparation, especially when it comes to Mahar (an obligatory wedding gift in Indonesia). Some people the mahar is given in the form of money and the amount of money for mahar is adjusted with the wedding date. For example if the wedding date is 15 June 2013 the mahar would be 15.062.013.
Since 1, 5, 10, or 50 is no longer circulated in the current Indonesian currency, you should find bank note issued in the past. Searching this type of old bank notes or coin is not really difficult in Jakarta. One of the places that you should search is in Passer Baroe. There are a lot of street vendor who sells old Indonesian bank notes and coins.
Mostly the street vendors are start selling from 10.00 to 16.30. You can find old Indonesian bank notes and coins issued in 1950’s to 1990’s. If you need to find the old foreign currencies, you can find it here too at Passer Baroe.
But still mostly the foreigners know more about the high value of antique rupiah than Indonesians, since they’ll already know what type of rupiah they’re searching for, including the denomination, the year it is issued, and the amount they need
So do you want to collect the old Indonesian currencies?
