Date In Old Indian Coin - Help Please.

Hi Seeker55 - I deliberately didn't post the weight and diameter as I was hoping to have another go at identifying it with a bit more info on the date. The measurements are:
Diameter ~18mm
Weight ~9.9g
Material - copper

I tried 880 and a few other dates earlier but not 809. Can I ask what characteristics indicate a sultanate coin?

Thanks

Thanks for posting the weight and diameter. In general, all available information is needed to ensure correct attributions of Indian coins.

Yes, andyg is right, Sultans of Jaunpur. A billon tanka of 80 rati, Ibrahim Shah, AH 804-844 = AD 1402-1440, GG J6. (So a date of AH 809 makes sense). The date was a bit confusing on this one - I can see how it could be read 880 or 911 as well as 809.

For me the writing style indicates a Sultanate coin. Also, I have one of these, so it looked familiar, especialy the distinctive part about 9 o'clock toward the center on the third photo.

As for how to tell Sultanate coins from Princely states,
Sultanate coins are usually text on both sides, Princely state coins tend to be cruder with partly pictorial designs... although not always!

With Zeno and dates - use a date range rather than the exact year if you can't find it first time, these Tanka's were issued over many years and Zeno may not have one dated 880, but there are lots of similar coins with dates close to 880.

lot's of J27's here,

This coin is of Husain shah bin Mahmud shah bin Ibrahim shah who ruled Jaunpur Sultanate.
