Sometime this coin makes me wonder, is this a real coin? With 7 dots on its obverse, this coin is still shrouded with mystery. Purposely made for petty cash in bazaar or wet market in Johor Sultanates, this coin is one of the many varieties of Johor's katuns. Their price is very low, since very few people have interest in them, I want to try to complete every varieties. Even I already have 2 varieties which are currently unlisted.
Currently genuinity is a major problem for Malay Sultanate's coins, since no one can confirm whether these coins are genuine or not. Does carbon dating technique can solve this problem? Or compositional analysis?
