Hi! The value of the coin will depend on many things. 1862 was the first year of that series of coinage after the transfer to direct rule by the British Crown iirc. There were four denominations that were minted that year in silver, all of which are .917 fine silver.
They are:
2 Anna, https://en.numista.com/catalogue/pieces18622.html ;
¼ Rupee (4 Anna) N#18983
½ Rupee (8 Anna) N#17813
and 1 Rupee. N#3345
These links will take you to the numista page for these coins and you can see the value depending on grade, year, mint, strike and variety. This assumes the coin is authentic. You can also post pictures of the coins you are asking about.
Cheers!
