This exceptional 1 Rupia silver coin from Portuguese India, minted in 1881 during the reign of King Luís I, represents a fascinating piece of colonial numismatic history. Struck at the Calcutta mint, this rare silver coin features the distinctive profile of the Portuguese monarch who ruled from 1861 to 1889. Composed of .917 fine silver and weighing 11.66 grams, the coin showcases the skilled milled (machine-struck) craftsmanship of the era, with its elegant 30.5mm diameter making it a substantial and visually impressive specimen. The 1 Rupia denomination, valued at 16 Tangas or 192 Réis, was the standard circulation currency of Portuguese India from 1880 to 1958. This particular coin carries significant historical weight as a tangible connection to Portugal's imperial presence in India during the late 19th century. Now demonetized, it has transformed into a highly sought-after collectible for numismatists and history enthusiasts alike. The rarity of well-preserved Calcutta-mint examples, combined with the coin's historical significance and substantial precious metal content, makes this an excellent addition to any serious collection or a compelling investment piece for those interested in colonial coinage and Indian numismatic heritage.
