the first coin is 1995 B.S. (@paisa) As per Nepali calendar so AD would be 1938, here in the same series there are lot of variations so refer to this

the second one is much older (1 paisa) during the period of our first king Prithvi Narayan shah (who united the grater Nepal, The first King of Grater Nepal) and His name is on the coin, From what I see the coin could 1952-1953 B.S (1895-1896)as not so clear but is the series from this
