Hello Milind,
India Republic 5 Rupees (Mother's Health is Child's Health) - KM 159
I see a note in the date field -
"The list of years is complete and has been verified. Most requests to add new year entries are sent for the wrong coin type. If you are sure you own this coin with a date that is not listed here, you can ask to have it added through the forum and include a picture of your coin in your message."
Can you post an image of the coin with the mint mark showing?
