WARRING STATES:LOT of 3 bridge money, curved bronze qing with suspension loop at top and minor decorative elements, one with dragon heads, average circulated condition, retail value $300, lot of 3 items. Though colloquially known as bridge money, these bronze bridges are formally known only as funerary objects designed to imitate the stone chimes of the bianqing. Bridge Money pieces have now been dated to circa 306-221 BC and are accepted by many - but not all - Chinese numismatists as actual coins of Ba and Shu States during the Warring States period.
