Old Malaya Currencies

I am a newbie in the fascinating world of numismatic. Only started my involvement sometime in the mid of 2012. However, due to my blessed union with my ever willing to share sifu's, I managed to get a rather handsome collection.

Uncirculated  (UNC) 1/2 cents 1945 Nederland Indies. It's not easy to get UNC condition pieces. Most in peoples collection are circulated pieces.
