This is a recently acquired and second example of a gold leaf covered bronze cowry shell of ancient China.
These are not completely understood as to their place in monetary history. Most likely they were used after real cowries had been replaced by imitations of made of many materials. They are most often found in graves which conveys the respect, associated with value, shown to the deceased. Actually, these very early objects of value' are the first bimetallic and clad 'coins' in history. The gold foil style of coating ended use in China ca. 600 B.C. Lacquer was used to apply the gold. Mercury fire gilding was used after this time.
