Jhalawar, Indian Princely State? [solved]

The seller believed this coin to be a 1 Paisa coin from Jhalawar. He had marked it as "KM 1132", but did not note the date of the coin or any other information.
I picked it up from the person he sold it to, so I can't ask him for the date. It is about 17 mm on the long side and weighs approx 8.6 grams. I want to add it to the catalog but I would like to make my submission as accurate and complete as possible.
Thank you!

This doesn't match any coins from Jhalawar in either Krause or Zeno.

A search of Zeno revealed that this is a dokdo from Nawanagar, Shri Jamji, KM 02, frozen date AH 978.

Thanks Seeker55.

https://en.numista.com/catalogue/pieces48832.html has the same KM number, but https://en.numista.com/catalogue/pieces40318.html says the right date as the coin you linked (AH 978 frozen)

Is my coin the same as either one of those Numista entries? I can't read anything on the coins, so I don't know what is/are the important part(s).

Thanks!

I'm not able to read anything on the coin either, but Krause's "South Asian Coins and Paper Money" says these coins were made from 1570 to 1850 AD. It says the earlier issues are heavier than the later 7-8 grams, so at 8.6 grams yours is an earlier issue. The frozen date of AH 978 is of course meaningless. I would say yours is KM #2 (the first coin you cite), an early version. I don't see the Y numbers in Krause, but it appears that Y#3 (the second coin you cite) is the same as KM#2, so it appears to be the same coin, in a long production run with slight variations. Nice piece of history!

Thank you Seeker55.

If you don't mind my asking, is there a technique you use to identify coins that you can not read? I can do reasonably well with many modern coins. However, ones like this are very difficult for me to recognize how much agreement is enough, and what parts are the ones that really matter.

Thanks

Sure, generally I look for the unique or unusual features visible on the coin. Then usually I do an advanced search on the Zeno database, putting in the weight and diameter range bracketing the coin, and putting in the category, such as India or Islamic.

If there are 100 or less matches, it doesn't take long to scan them all, looking for the unusual feature. Meanwhile I make a note if there are other coins that aren't a match but are similar in style, so might be from the same kingdom, ruler, or mint.

Thanks!
