Comment
This mint had 15 furnaces and cast 33,000 strings (33,000,000 individual coins) a year.Interesting fact
One interesting fact about the Yongzheng Tongbao (Boo-chuwan) coin is that it was the first coin in Chinese history to feature a unique symbol on the reverse side, which was a small square hole in the center of the coin. This hole was known as the "inner hole" or "niuchu" in Chinese, and it was added to the coin to prevent counterfeiting. The idea behind the inner hole was that only the official mint could produce coins with this unique feature, making it difficult for counterfeiters to replicate the coin. This innovation in coin design helped to increase the trustworthiness of the currency and reduce the prevalence of counterfeit coins in circulation.
