This 1990 publication by the Malaysia Numismatic Society besides the article by Mohd. Kassim Hj. Ali on
Hoard of Malay States Coins Found At Tanjung Pinang, Riau Islands, Indonesia includes 2 more articles on tin currencies of the Malay Peninsula. First,
Tin Coinage of Sultan Ali Iskandar Shah of Johor (1855 - 1877) by Ishar Abdul Latiff and
Unlisted Tin and Gold Coins of the Malay States of Johor, Terengganu, Kelantan, Kedah and Perak by Saran Singh.
Published more than 20 years ago in limited print, it is very difficult to get a copy of this publication. The best bet would be from members of the society who were members at that point in time.
Being a collector of Animal Currency I can't help but to appreciate a tin cockerel item included in the back cover advertisement of K.L. Coins & Curios Centre owned by Tony Lye Fong Nge. This outlet that was located at Sungei Wang Plaza in Jalan Bukit Bintang, Kuala Lumpur has since ceased operation. Presented below is the said item.
