I don't think any are Nepalese. Top left is from the Indian Native State of Indore, and , depending on size, will be a half paisa, quarter anna or half anna, in the reign of Shiraji Rao (AD 1886-1903). Top right is possibly upside down. I think it is a pie, paisa or two paisa from the Indian Native State of Baroda, in the reign of Sayaji Rao III (AD 1875-1939). Not sure about the other one. Regards Gary
the top two are indian princely states the one on the right as i look at is from baroda, the one on the left is from indore, but the one underneath is from tibet, and looks like a 1920's 1 sho.
