Hey Bonedigger, not bad. I've got a very similar one, but the dealer I bought mine off couldn't put an exact date to it, and I never thought to check to see if it had a readable date... until now

. So thanks for the post!

So, you may ask, where are the dates on these coins? The pic of the reverse of yours (the pic on the right side), Bonedigger, is upside down. Here it is, right-way-up, with the date highlighted down the bottom:

The numeral system isn't quite the same as modern "Arabic" numerals - but they're close enough. Yours is clearly "919".
Here's mine, for comparison:

. The date is almost off-flan, way down in the bottom left corner, but it's still readable. The second digit looks a bit like a "Western 4", with the best fit in Arabic being "6"; that would make the date "961", which would not fit the attributed Sultan's timeframe (AH 917-937). So I needed to know how the Malwanese (

Malwanians? Malwanids? Malwanites?

) wrote numbers.
I did a bit of Googling and found an excellent compilation of coinage from this Indian State on the
South Asia Coin Group website. On their third one down, dated 921, the "2" is written backwards, the same as mine, so I now know the date on my coin: AH 921, or 1515 AD

.
Thanks again for the prompting, Bonedigger!
