Help With Unknown Thick Silver Coin.

I believe it's 19th Century Sikh... Have to double check on that. I have a couple much like it. Beautiful, isn't it?

Why did you buy a coin you don't know anything about? Hopefully you didn't spend too much, these are not expensive typically, and yours isn't in bad shape, but it's far from Mint State.

I love the feel in my hand, it has real weight despite it's small size. Feels like MONEY. Congrats on your new purchase!

I edited your title a bit to draw more attention from our members ;-)

All the explanations are correct.
Here some more :
The little marks on the rim are made by tradesmen to show that they accepted this coin as legal tender. Each had his own symbol.

A lot of indian coins were made 'in the name of Shah Alam II'

Info from the Krause catalog:
The rulers of Pratabgarh, a state located in northwest India,
the maharawals, were Sesodia Rajputs who are believed to have
migrated in 1553 from Mewar, where their ancestors once ruled.
Arriving in the area they seized control from the local Bhil chieftains
but it was not until the early 18th century that Pratabgarh
town was founded by Maharawat Partab Singh. Pratabgarh was
tributary to Holkar until 1818 when, with the collapse of the Maratha
states, the state came under British protection. The state
was then managed through the Rajputana Agency until, in April
1948, it was merged into Rajasthan.

corrections welcome
