Help cataloging this Indian coin.

Hello community, a few months ago I got this copper coin. I was told it is 1 Paisa from the Sikh Empire. 

Although I can't locate it. From what I see it seems to be a mule or hybrid coin, I said this because its obverse it looks like the “Paisa KM# 7.13 of the Sikh Empire”. While the reverse is identical to “1 Paisa KM# 39, 29 or 28 of Jaipur State”.

The problem is that I can't find anything similar, it may be a copy of Loharu, but I also didn't find anything similar in that section within the Zeno.ru page and Google.

This will be an issue of the Loharu mint who copied coins in the style of Sikh paisas and coins from other states, between 1845 and 1865 there were 52 illegal mints operating. Countless  thousands of  paisas and  takkas of Bikanir, Jaipur and other states were produced. Many collectors will be unaware that they have examples struck here instead of the official mint.

 In 1849 the British abolished Sikh  coinage but the villagers  went on demanding the dumpy coppers for a long time and the minters copied the originals less closely as they were no longer legal tender
