Interesting! It does look like some of those Sigismund III Polish coins! Is this the Jahangir referred to? He's also from the 17th century, albeit a bit later. There must be some explanation- some European trading post in that part of India, perhaps? This is beyond the scope of my knowledge. PS- I can't make out the Latin text. It does seem to at least partially resemble the inscription on Netherlands ducats, though. @GDJMSP knows a thing or two about ducats, though I don't know if he'll be able to shed any light on this Indian coin or not. @coin_nut knows a thing or two about Dutch East India Company coins, so I'll tag him as well. Interesting hybrid.
I realize that nothing was intended other than professional curiosity, but many people do not specify country or city or more online since we have about 50 bots monitoring the exchanges for their own purposes. Welcome Muhammad, Jim
I missed out on buying this. A man was selling it for 3$ only. I hate myself. He claims its a portuguese mughal strike from goa. but hes not sure, and it doesnt look to be of any portuguese design as well.
I have never seen anything like this. As @lordmarcovan pointed out, the reverse resembles Netherlands ducats. It doesn't just resemble the ducats posted, it is the same inscription, but blundered. A blundered inscription means an unofficial coin. I found a listing for a Southeast Asian contemporary counterfeit ducat. Perhaps there were also contemporary counterfeits in bronze? https://auction.sedwickcoins.com/Netherlands-East-Indies-imitation-ducat-dated-1595_i33011463
Wow, what a great find, an indianized Dutch gold ducat! A Dutch helmeted soldier, not square and stocky, but willowy like a Gupta god.
