Hello for any of you wishing to visit Indonesia.
Besides temples and interesting shops, Yogyakarta also has a budding numismatic community.
Every 2nd Sunday of the month, there is a small bourse in the main hall of the GPO at the bottom of Jalan Malioboro in the center of town. Just tell your driver "Kantor Pos Besar".
