China, Eastern Zhou, Warring States Period AE Ming Knife 440-222 BC (No reserve price)

The AE Ming Knife coin from China’s Eastern Zhou period, specifically the Warring States era (440-222 BC), is an excellent example of ancient Chinese currency evolution. During this era, metallic knife-shaped coins emerged as one of the various regional monetary forms before standardized round coins with square holes became dominant. These knife coins, often crafted from bronze, symbolized the intersecting influences of utilitarian objects and currency, reflecting both practical and symbolic functions. Their forms vary by state and period, with decorative or inscribed sides indicating origin or value. Collectors and historians value such coins for their unique shapes and the insights they provide into China's complex early monetary systems and regional powers preceding unification under Qin.
