The first coin is an off-center strike. The planchet (piece of metal that is struck to become the coin) was not properly in place between the dies when they cam together. I can only comment as to rarity of what such a coin would be if it was a US coin. Off-center coins are rare as compared to the number of coins struck, but are actually a fairly common type of error coin. If this was a US coin it would probably be a $40 - $50 coin because of it's age. If this was saya 2006 off-center nickel, it might be a $10 - $15 coin.
The second coin is an early stage full brockage. A coin was struck and then instead of being ejected for the press it stuck to the die. The the planchet for this coin was fed in and struck between the die and the previously struck coin. On one side the metal of the planchet flowed into the die forming the raised image of the head and lettering while on the other side the heand and lettering of the struck coin was forced into the planchet creating an incuse reversed image. A full brockage is a much rarer form of error. On a US coin of this age it would be worth several hundred dollars. Even a recent coin would be at least a couple of hundred.
How these values would translate to Indian coins I don't know. Being non-US, interest would be much lower here than for US coins, and I don't have any idea how much demand for them there would be in India.
