China issues commemorative coins for world heritage site 'Liangzhu City'

China's central bank issued a set of commemorative coins on Monday featuring the Archaeological Ruins of Liangzhu City, which is a UNESCO World Heritage site.

The set includes one gold and two silver coins, all legal tender, the People's Bank of China said.

All coins feature the national emblem on the obverse, while the reverse is inscribed with Chinese characters reading "World Heritage" and "Archaeological Ruins of Liangzhu City."

The gold coin, which is 22 mm in diameter, contains eight grams of pure gold and has a face value of 100 yuan (about $14.16).

One of the two silver coins, with a diameter of 90 mm and 500 grams of silver, has a denomination of 150 yuan. The other silver coin, with a diameter of 40 mm, contains 30 grams of silver and has a denomination of 10 yuan, the central bank said.

The Archaeological Ruins of Liangzhu City, located in East China's Zhejiang province, have gained worldwide recognition as bearing testimony to the existence of at least 5,000 years of Chinese civilization. They were inscribed on the World Heritage List as a cultural site last year.
