Overview
A fascinating mixed hoard featuring traditional Chinese 'cash' coins with square holes alongside early 20th-century Japanese machine-struck coinage. These pieces represent the transition from ancient casting methods to modern industrial minting in East Asia.
Story
For over 2,000 years, square-holed coins were strung on cords like beads for easy transport. This set includes Qing Dynasty issues and Japanese 5 and 50 yen coins, bridging the gap between ancient silk road trade and modern commerce.
Maker / Origin
The cast coins were produced by government mints like the Board of Revenue in Beijing using sand-casting techniques. The round-holed and solid coins were struck by the Japan Mint in Osaka, which was established in 1871 using imported European machinery.
Condition & Value
The coins show significant circulation wear and varying degrees of oxidation (verdigris). The heavy green patina on some cast coins is natural but obscures detail; cleaning is not recommended as it destroys numismatic value. The condition is average for 'found' hoards.
