1964 - Jawaharlal Nehru Pattern Rupee Coin

The pattern or experimental coin represents one of the most intriguing and elusive issues associated with India's first commemorative coin, issued to mark the Birth Anniversary of Jawaharlal Nehru following his demise in 1964. 

For comparison, the approved coin is shown in the second image, enabling collectors to readily identify the differences between the experimental version and the adopted design.

The coin issued for Proof sets and regular circulation differs from this rare pattern, which exhibits several distinct design differences, indicating that it was prepared during the developmental stage before the final design was approved for mass production.

The reverse portrait of Jawaharlal Nehru differs significantly from the adopted design. The overall relief of the bust is noticeably higher, giving the portrait a stronger three-dimensional appearance. Nehru's facial features are more sharply defined, with prominent cheekbones, deeper contours, and a more mature appearance. The hair is engraved with finer and more pronounced strands, while the bust itself is both wider and taller than that seen on the issued coin. These differences suggest that the engraver experimented with a more sculptural representation before the final portrait was simplified for commercial minting.

The obverse also displays several noteworthy distinctions. The Lion Capital of Ashoka appears more detailed, with sharper engraving and greater definition throughout the design. The lettering on both the obverse and reverse is slightly thicker and bolder than on the circulation and Proof issues, giving the pattern coin a distinctly different visual character. 

This remarkable pattern has been certified by NGC as PF66 and described as "Extremely Rare." It appeared in Todywalla Auctions 157, Lot No. 516, in July-August 2026, with a pre-sale estimate of ₹2,25,000 to ₹2,75,000. Another example, an ungraded Pattern Rupee, was previously offered in Todywalla Auctions 115, Lot No. 1109, where it realized ₹2,25,000 in April 2018. The appearance of only a handful of specimens in major auctions over several decades underscores the exceptional rarity of this issue.

The designation "Extremely Rare" strongly suggests that only a very limited number of these pieces were produced, consistent with the nature of internal Mint trials. Unlike circulation or Proof coins intended for public distribution, such experimental pieces were generally manufactured for internal evaluation and would ordinarily have remained within the Mint. Their survival outside official channels likely resulted from a small number of specimens being retained, officially presented, or otherwise leaving the Mint through undocumented means.

Without access to official Mint records or Government documentation, the precise purpose of this Pattern coin cannot be established with certainty. It may represent a true pattern coin prepared for design approval, where alternative portraits and inscriptions were evaluated before selecting the final design. Equally, it may have served as an experimental strike to assess die engraving quality, relief, metal flow, and striking characteristics before production commenced. The extensive modifications to both the portrait and reverse, however, lend stronger support to its classification as a genuine pattern rather than merely a technical trial strike.

Regardless of its exact classification, this Pattern Rupee remains one of the most important and desirable modern Indian pattern coins known to collectors. It offers a rare glimpse into the artistic and technical evolution of India's first commemorative coinage, illustrating how engravers and Mint officials refined the portrait, lettering, and overall composition before the final design was released. Such pieces provide invaluable insight into the coin-design process and preserve an otherwise undocumented chapter in the history of the India Government Mints, making them highly significant from both numismatic and historical perspectives.
