| Additional information |
The Board of Revenue Mint in Beijing — one of the two central imperial mints — operated under unusually close bureaucratic scrutiny, with coin weights and alloy ratios audited by ministry officials rather than left to mint supervisors. During Jiaqing's reign the brass composition of cash coins became a persistent administrative headache: copper shortages pushed the actual alloy ratios into repeated noncompliance, and provincial mints were periodically suspended for debasing their output while the capital mints were held to stricter account.
