Netherlands indies coin: First coinage

one of my hobby is looking for an old coin. Some of them you can buy at a cheap price as long as you know where to look. I bought this coin in penang this year. The condition of this Netherlands indies coin: First coinage ain't very good but still a good collection for me.

The Netherlands Indies is a group of four large and some 3,000 small islands between southeast Asia and Australia. The home of earlier Buddhist and Hindu cultures, it became Islamic after the 12th century and was taken over by the Dutch in the 17th century. Following Japanese occupation during World War II, it became the independent republic of Indonesia in 1945. Capital: Batavia (now Jakarta).
