E) This new discovery in 2002-2005, mostly found are Portuguese coins in form of Dinheiro and Bazarucco, but, most of the tin coins are seriously eroded and highly oxidized, due to the movement of shallow fresh water of Sg Melaka (Melaka River), not like those found early in 1970 – 1980, from the thick black muddy areas of sea front of Straits of Malacca along the Bandar Hilir to Klebang Besar, especially those areas within the complex of Kompleks Warisan Melaka, that is why most of the tin coins contained in this well protected mud, deep in the 2-5 meter sea water, when discovered from this areas, are found in good condition, some remain intact, with clear design and wordings.
