Stange little item. Nepalese Copper Ingot?

I got this item as part of a group lot.  I originally set it aside because I didn't think it was anything of value and didn't think it was a coin at all.  The other coins in the lot that it came in have been from India, Nepal, Kushan, Tibet.  Mixed in were also some Roman coins but I think those were added by the dealer as the whole thing was an "I don't know what these are job."  I tried asking about the providence of the coins, but they have been there so long no one remembers where it came from.

So I finally came around to this lump and started doing research.  My thinking was that the original owner must have know it was a coin, of knew the providence and it was lost or thrown away when sold because the buying didn't understand the meaning of the annotations.  Based of the company it was keeping with the Indian, Nepal, Kushan coins I started my search there.

I have found reference to what is called Lohiya Paisa.  Basically small ingots of copper varying in purity that were used as small change in eastern Nepal.  The weight for an ingot the was equal to 1 Paisa is supposed to be 8-12 grams.  This would put my example at the low end of the scale but with in range.

From the Encyclopedia Britannica:

Цитата"The other, the Lohiya paisa, is also a rough square lump of copper, but is much adulterated with iron. It is chiefly used in the eastern districts."

Weight: 8 grams
Dimensions: 10 mm x 5-6 mm

Apologies for the slightly blurry pictures, it is overcast today so my natural lighting is not as good as it sometimes is.



Here you can see some cut or saw marks on the side.  



There do not seem to be any identifying marks on the ingot, which from what I have read would be indicative of the Bhutwaliya paisa, another system of copper ingots that were also used as small change but had a much higher purity.

Has anyone seen anything like this before, or have any other ideas?
