This is a rare 1.60g solid 18K gold coin from the Kushan Empire era and Indo-Greek period. The coin was discovered underground in Afghanistan and its composition is pure 18k gold. It is ungraded and uncertified with no certification number or date of origin. The denomination and KM number are unknown, but it has been cleaned and is in good condition. This coin is a valuable piece of history from the Greek (450 BC-100 AD) period and is a must-have for any ancient coin collector. I used to have a certificate of authentication. If I can find it, I will include it with the coin, but I can't  guarantee it. It come with a sterling silver bezel, so you can wear this piece of history on a necklace.
