How to read the mint mark

This issue came from Calcutta (Kolkatta Mint). The mark sits under the year on the coin: a diamond or dot for Mumbai, a star for Hyderabad, nothing at all for Kolkata, a solid dot for Noida. Year and mint together identify a variety; neither does it alone.

What a catalogue figure is, and is not

It is a reference for one variety at one stated grade, not an offer and not a market price. What a specific coin fetches depends on who wants that exact piece on that day, and on a condition assessment that usually has to be seen rather than described. Two coins of the same year and mint can sit two columns apart in the table above.

Where this leaves you

If you are holding one, compare it against the table above by year and mint, and judge the condition strictly. Every other denomination is catalogued here, and if you decide to part with it, this explains how selling actually works.
