The standard answer and feedback are:

“…..those “Big and Medium size Crocodiles and Tortoise, animal money”…were found from Pulau Besar and its surrounding islands and seafront of Straits of Malacca”, may be due to the sensitivity of :-
(A) enforcement units of government agencies, like PERZIM, Marine Police & etc….
(B) commercial sensitivity of their income by revealing the locations and sites….
(C) or those items are found somewhere not in those areas they specified….anyway, MAM is very conservatively to observe all these development…we doubted….


One fundamental element our MAM noticed is: from those hundred pieces of tin money we authenticated and tested, having their common characteristics and similarities, that's


(A) those items are quite highly eroded and oxidized, and deeply muddied , like weathered….some with “crystal” encysted …these elements are highly impossible for anyone to artificially manual it; (some parties tried to replicate, but failed, doesn’t have that original shape, soft & new outlook, uncomfortable to touch and to see)

(B) instinct reading of human eyes, feeling and touching of its natural texture of : “ weathering, oxidization and erosion, with time consuming “sea water pressure and penetration of mudding chemical reaction” on surface & structure of tin money , is one of those things who can’t blind the eyes of appraisers and authenticators….on those newly minted and those found above sites.

(C)The question is Dating (When) and Place of Origin (Where)….no doubt, all interested parties have to address it professionally, academically and scientifically

This is our biggest challenge, hence our Museum proposed to set up a professional working team, work closely with PERZIM & Muzium Negara, to conduct this archaeological study and academic research, consists of competent and qualified personnel, as what we proposed to PERZIM early.

This is only our presumptive circumstantial evidence to circumstantiate these tin money found in Melaka..…hoping that is not the paralogism….anyway, this is my personal legitimate inference :- based upon the areas and years of artifacts of “ tin money and ceramics of Song/Ming Dynasty” found from the common sites of above mentioned…with what Department of Chemistry of Malaysia reported for those 16 items artifacts analyzed and tested scientifically and academically in 2002, by Government of Malaysia, also those relevant parties and person interviewed regarding the manner and method of finding the artifacts and tin money.

We must admit that we still facing many problems of insufficient archaeological data and academic research papers, to substantiate the legitimate claims of locations where artifacts discovered, all parties have to work closely and jointly to reinforce these shortcomings, spirit of complementary and supplementary shall prevail in this respect.
