Since the fabrication of old Chinese coin was in China and also its production is not continued at the recent day causes the Balinese peoples difficult to obtain it. An effort to produce a local made Chinese coin is then promoted but the result is not satisfaction because the appearance especially the color is not mach with the original one due to metal composition of old Chinese coin is not recognize. The old Chinese coins that are found in Bali are recognized come from several dynasties in China. For this purpose one by one of the old Chinese coin which are depend of the dynasty that produce the coin should be investigated.

It is found that the metal composition of the northern Song Dynasty of old Chinese coin that was found in Bali island are made of copper (Cu) that reach about 62.221wt.% followed by tin (Sn) about 22,98 wt.% and lead (Pb) about 6.644 wt.%. Surprisingly that the coin just contain about 0.238 wt.% zinc (Zn) that mean the coin is in category as a bronze and not as a brass. Other trash element that are found are iron (Fe) about 2.611 wt.%, vanadium (V) about 0.062 wt.% and also titanium (Ti) about 0.424 wt. % as supported by metallography analyses.
