Abstract
The results on elemental analysis of the vietnamese ancient bronze coins during
the time of the Nguyen dynasty (19th century) are presented. The samples were provided by
the Vietnam National Historical Museum and the elemental analysis was performed on the
home-made model EDS-XT-99-01 X-ray fluorescence spectrometer in the Institute of Materials
Science, NCST of Vietnam. The samples exited simultaneously by radioisotope source
and X-ray tube. The analytical results show the similarity in the elemental composition of
the coins issued by different kings of the Nguyen dynasty, but there is the difference in the
concentration of the used elements. Another interesting point is that all the coins have zinc
(Zn) in their composition, which shows clearly the influence of the occidental metallurgical
technology on the money-making technique in Vietnam during the 19th century.
