Thick Rupee of George V in 1913

George Frederick Ernest Albert, remembered as King George V, ascended the British throne on 6 May 1910 following the death of his father, King Edward VII. He reigned as King of the United Kingdom and the British Dominions, while simultaneously holding the title of Emperor of India, until his death in 1936. Born during the reign of his grandmother, Queen Victoria, George V was not originally expected to inherit the throne, being the second son of the future Edward VII. Nevertheless, his reign became one of the most significant periods in British imperial history, encompassing the First World War and major constitutional transformations throughout the Empire. The coinage issued under his authority remains one of the most extensively collected and researched series of British Indian numismatics.

The One Rupee of George V was struck between 1911 and 1922, representing the principal silver denomination of British India during the early twentieth century. From 1911 to 1920, production was shared between the Calcutta and Bombay Mints, whereas the final issues of 1921 and 1922 were produced exclusively at the Bombay Mint. Throughout the series, the Rupee retained its traditional milled (reeded) edge, with standard circulation pieces averaging 11.6 grams in weight, 30.5-30.8 mm in diameter, and approximately 1.9 mm in thickness. These specifications remained remarkably consistent, reflecting the strict quality standards maintained by the British Indian mints.

While examining this series, I encountered an unusual group of George V Rupees that differs subtly from the documented mint specifications. These specimens retain the standard diameter, overall design, and edge characteristics of regular circulation strikes, making them virtually indistinguishable through casual visual examination. However, detailed measurements reveal a consistent thickness of approximately 2.0 mm and an average weight of about 12.3 grams, representing an increase of nearly 0.7 grams over the officially documented standard. Despite this additional mass, the coins display no obvious design alterations, surface irregularities, or evidence of post-mint modification.

To date, I have identified three specimens exhibiting these same physical characteristics. Their remarkable similarity in appearance, dimensions, and increased weight suggests that they are unlikely to be isolated measurement anomalies. Instead, they may represent a previously undocumented production variation, the result of unusually thick planchets, an experimental striking, or another form of mint manufacturing deviation. Because the coins exhibit no discernible visual differences from standard issues, their distinctive characteristics become apparent only through careful physical examination and precise measurement.
