Indian Mints: Symbols, Secrets, and Stories
1. Mumbai Mint (Earlier Bombay Mint)
Key Mint Marks:
- Diamond Under the Date: A rare mark used only once in 1989 for the Jawaharlal Nehru UNC (Uncirculated) Sets.
- “B” Under the Date: Indicates coins struck in Bombay (pre-1996).
- “M” Under the Date: Post-1996, the mint adopted “M” for Mumbai.
- “U” Under the Date: Exclusively used in 1989 to denote UNC sets, a practice discontinued afterward.
History & Significance
The Mumbai Mint, established in 1829, is one of India’s oldest and most iconic mints. Its mint marks reflect both geography and experimentation. The 1989 Jawaharlal Nehru UNC set is legendary among collectors due to its unique “U” mark, intended to distinguish uncirculated coins. However, this system was abandoned, making these coins rare artifacts. The shift from “B” to “M” in 1996 mirrored the city’s official name change from Bombay to Mumbai.
2. Kolkata Mint
Key Mint Mark:
- No Mint Mark: Coins from Kolkata lack any visible identifier.
History & Significance
Established in 1757, the Kolkata Mint is India’s oldest operating mint. Its lack of a mint mark is deliberate—coins without marks are assumed to originate here. This tradition dates back to British colonial rule when Kolkata (then Calcutta) was the primary minting hub. For collectors, the absence of a mark is itself a clue, linking coins to Kolkata’s rich legacy.
3. Hyderabad Mint
Key Mint Marks:
- Star Mark (⭐): Used on commemorative coins.
- Dot in Diamond: A modern mark for regular-issue coins.
- Split Diamond: A historical symbol phased out in the 1990s.
History & Significance
Hyderabad Mint, operational since 1803, is renowned for its intricate marks. The “Split Diamond” was its hallmark until the 1990s, when it transitioned to a “Dot in Diamond” for everyday coins. The star symbol, however, is reserved for special editions, such as the 2010 Commonwealth Games commemoratives. These marks reflect Hyderabad’s blend of tradition and adaptability.
4. Noida Mint
Key Mint Mark:
- Thick Dot (•): A bold dot under the date.
History & Significance
Established in 1988, Noida Mint is India’s youngest mint. Its thick dot mint mark symbolizes modernity and precision. Unlike other mints, Noida focuses on producing stainless steel coins, which are durable and cost-effective. The dot is simple yet distinct, mirroring the mint’s efficient, no-frills approach.

10. Tower Mint (UK)
A private mint specializing in custom coins and tokens for over 50 countries. Its “TM” mark is seen on collectibles worldwide.
Why Mint Marks Matter
Mint marks are not just identifiers—they are cultural fingerprints. For India, they chronicle the evolution from colonial rule to modern republic. The Bombay “U” mark, for instance, symbolizes a fleeting experiment in quality control, while Kolkata’s blank coins whisper tales of British India. Globally, mints like the Royal Canadian or Pretoria reflect economic power and artistic heritage.
For collectors, these marks turn ordinary coins into historical artifacts. A 1989 Nehru coin with a “U” or a Hyderabad Split Diamond coin becomes a tangible piece of legacy.
Conclusion
Next time you hold a coin, look closer—the tiny symbols beneath the date might just reveal a journey across centuries and continents. Whether it’s Mumbai’s elusive “U” or Pretoria’s golden Krugerrands, mint marks are a silent dialogue between the past and present, waiting to be decoded.
