As one of the pioneers of modern Chinese coins, dealer/collector Xiyu (real name Ding Feng) publishes price guides for MCC regularly on jibi.net. They reflect the general trend of MCC pricing in China. Although it is in Chinese, Google Translate does a good job translating most of the content. Both mintage and current market prices are listed for rare coins. Coins are listed by category in separate posts. The price is in the Chinese Yuan. "w" in the lists means ten thousand.
This price guide can also be used as a pick list for those who are not sure what to buy for MCC.
