Watch List notes:

ZHOU:LOT 5 pieces of "bell money" (zhong qian or ch 'ung), Spring-Autumn Period, 770-476 BC, one piece with intact clapper, average quality examples, retail value $450, lot of 5 items, ex Charles Opitz Collection. Opitz lists these with the comment that they were not currency, but are included in many collections. For many years they have been considered a form of money by some authors, but these have been found in tombs as sets of bells used for making music and sets include small bells up through large ones, each probably playing one note. Whether currency or not, they are still interesting artifacts.

Estimate: 150-250 USD
