I was browsing Ma-Shops and saw this newly listed coin, while it certainly looks like an archaic Greek issue, i'm sure it comes from the Southeast Asian islands of Indonesia, probably Mataram kingdom circa 10 century AD (@TuckHard can chime in here for better knowledge). Still an interesting coin from an underrated region, even the weight 2.4 g comfortably sits at the range of 1 massa denomination. Here is the listing https://www.ma-shops.com/agola/item.php?id=4241
Good eye on this! I've seen another listing go to auction in the past with the similar mistaken identity. Yeah this is definitely a Javanese silver coin, these were first produced around 780 AD or soon after by the Mataram Kingdom (also known as Medang or the Shailendra Dynasty) and was continued for around 500 years by successive kingdoms until the Majapahit Empire period when the native silver coins were abandoned in favor of imported Chinese copper cash which made small marketplace transactions much simpler than valuable silver coins. This example seems fairly early so I think a circa 10th century attribution is probably fair. Here are some of mine. The gold one at the end was made by the rival (and sometimes intermarried) royal family of the Srivijaya who were based on the nearby island of Sumatra.
