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

The gold commemorative coin, which is 22 mm in diameter, contains eight grams of pure gold and has a face value of 100 yuan (about 14 U.S. dollars) with Jade Cong – the most representative cultural artifact unearthed in Liangzhu Ancient City – and its unique decorative patterns shown on the back side.

With a diameter of 90 mm and 500 grams of silver, one of the two silver coins has a denomination of 150 yuan and was carved with the typical "deity and animal mask pattern," which appears on many of Liangzhu's cultural relics.
