India Falus? [решено]

I recently purchased a group of "Ancient" coins that I am trying to Identify (confirm). I have minimal information that was provided for each coin, but I am having trouble verifying the information provided, and filling in the gaps. I will list them each separately for help with these.

I have 2 coins with the same basic information.



Information provided with this one India, Ahmednagar Sultanate - Nizam Shahi, Falus. I couldn't match it to any listings in the catalog. The coin is 9.1 grams, and 17mm. I didn't measure the thickness, but it is a very thick coin. Metal composition unknown.



Same identifying information as above. This coin is 9.2 grams, and 17mm. Also, a very thick coin.

Thank you in advance for any information on these. Colin

I think both are versions of this, allowing for different dies and striking positions on the flan

The second coin shows a partial date on the bottom, appears to be AH 100X

Yes they seem to match the coin in the link. For my reference, where are you seeing the date on the second coin? The conversion table that I am finding for AH to AD is saying AH100x would be AD 718-719. Is that correct?

On the bottom of the second coin (left-hand photo) after the star there is a 1 then a dot and another dot. This means 1-0-0 in Persian numerals, and the fourth digit is off the flan. So the coin is between 1000 and 1009 AH.

To convert AH to AD subtract 3% (to convert lunar to solar years) and add 622 (the AD year of the prophet Muhammad's travel to Medina, the start of Hejira dating). Therefore 1000 AH = 970 + 622 = 1592 AD and 1009 AH = 979 + 622 = 1601 AD. So your coin is between 1592-1601 AD.

It should be kept in mind that AH and AD years do not exactly correspond, so a particular year in one system includes two partial years in the other system, and the conversion is therefore approximate, give or take a year.

Excellent!! I see that on the coin. Thank you very much for all the information.
