A mointor lizard was looking dor dinner in the river in Malacca. He is between 4 an 5 feet long. He couldn't hvae cared less if I was there, he just meandered around the sea wall dor quite some time before going down river. They told me it was unusual to see such a lagre one in the river they are usually much smaller.
How would you like to carry these "coins" in your pocket. They are made of tin , the larger ones are about 6" in diameter the smaller are 2". They were legal tender in the 13th century for the extensive trading done in Melacca, Malaysia. There are others like alligators, birds and fish. The size determined the value and were used throughout Southeast Asia.
