This is a very interesting book about the history and development of "Ringgit" or Malaysian currency during the colonial, pre-independence and post Independence. This book is co-published by "Lembaga Muzium Negeri Pulau Pinang" and "Pesatuan Warisan Numismatik Kesultanan Melayu, Malaysia". I am glad to obtain this book during my recent visit to Penang State Museum.
"Ceritera Ringgit" or The Chronicles of The Ringgit
Section 1 covers the trade currency and the origin of the Ringgit.
Section 2 gives information on the Ringgit and its supporting fractions
