You should know that all the coin actually is molded by same designed mold. However, our Malaysia coin factory also has his own problem in molding the coin before that especially at the year 2000-2002 , you will find that the coin actually is a little bit different in cutting and appearances as usual, someone said that it was because of the Perkilangan Syling Malaysia facing the technical problem and subcontract the project to other country. However, start from 2003 our coins actually as "identical same" with the mold start using at the year 1989 and only in different in year.
Try to compared carefully for this two coin, you will identify the problem of the fake coin. They are not the same, the track of the kite, the word style of "Bank Negara Malaysia", at the reverse even the security edge cutting of the coin which written "BANK NEGARA MALAYSIA" also not the same in length, more lighter only about 8.33g which 1 g more lighter than genuine coin.
As, conclusion it is fake coin!!!!!!
It was the latest news about the 50 sen fake coin.
However according to my experience, it is not the latest version of fake coin. The fake coin i shows actually is the old version of fake coin, which is very easy to identify. However, my collector friends told me that, the latest version even can said that more than 95% above is the same, even the bank machine also fail to identify. It only different in weight and BANK NEGARA MALAYSIA term at the reverse are a little shallow in track.
