Central China's Hunan Province is offering a reward to anyone who can decode the inscription on the back of six ancient gold coins.
The Cultural Relics Bureau of Jinshi City has offered 10,000 yuan, roughly 1,500 U.S. dollars, to anyone who can explain the mystery of the coins, housed in the city's museum.
A small white glazed pot containing six foreign gold coins was discovered at a farm in the 1960s and was sent to the museum in the 1980s. They are classified as top-level national cultural relics.
These coins were manufactured using ancient Greek coinage method at least 650 years ago. The inscription on the front, in a rare type of Arabic, is the name of a King, but the information on the back remains unexplained. Cultural relics officials have consulted Chinese and foreign experts, but to no avail.

Online retailer Amazon China has unveiled its annual list of most romantic cities, with Zhengzhou in Henan Province declared the most romantic Chinese city of 2015.
Zhengzhou led the country in the proportion of books sold last year on the topics of romance, relationship and marriage.
Cities of Erdos and Baotou, both in north China's Inner Mongolia Autonomous Region, ranked second and third.
Among the top ten, northern Chinese cities outnumbered the southern for the first time.
According to Amazon, the result does not necessarily mean that people in northern China are more romantic than their southern counterparts; and the ranking reveals many factors, not just the cultural environment of a city.
China's four first-tier cities, Beijing, Shanghai, Guangzhou and Shenzhen, did not feature in the top 40. Amazon says it appears that residents in smaller cities are under less pressure and have more leisure time to enjoy romantic literature.
