Mint Marks and Indian Coins

Every mint uses a distinctive mark to identify that the coin was minted from the said mint. The purpose of the mint mark is more for traceability purposes. India has 4 mints with some of the mints existing before Independence. The latest mint was established at Noida in 1988.

Over the years India has also used nearly 10 overseas mints from 1985 to 2001 to mint coins due to growth in demand and lack of capacity at Indian Mints. In these years 19 types of coins were minted by these mints in different years and of denomination from 10 paise to 5 Rupees. After the expansion and modernization program undertaken at all mints today there is sufficient capacity and Noida mint regularly mints coins for other countries that need such services.

This article gives out the details of the mint mark used and how to identify these.
