Approximately 25mm in diameter, the coins are thought to have been minted during the period of the Delhi Sultanates, who reined in north India from 1206 to 1526, and bear what is believed to be an Arabic inscription.
The heads of the coins portray the Monarchy title but the reverses have yet to be deciphered.
The gold coins were unearthed at a farm in Henan in the 1960s and are now in the local museum in Jinshi, Hunan.
