Mr. Nazhif telling me he has been looking for any information regarding this coin in the Internet since he inherited the coin from his mother. The coin actually owned by his grandfather who work in Bank Negara Malaysia a while back. He don't tell me what year but his name is Encik Basri Bin Adam. Who work as a coin maker in Bank Negara. I don't know if the information is real, try to search anything about Bank Negara staff list but look like that took some time to find.
All the coin design are almost the same. It still have Parliament house on the reverse and its value on the obverse. Mr. Nazhif telling me in his email that the first coin is thinner and smaller then normal. The coin color look like it is made of tin. The second design of coin look like it is made of copper with a scalloped edge. The third design look like it is made of bronze with same design from the original coin. Is this a trial pattern or unissued coin by Bank Negara for this coin? Anyone know about this coin? Feel free to share it in here or you can e-mail me at firstname.lastname@example.org.
