King William 1835 1 Rupee Calcutta Mint (F on Neck) XF coin

  The 1835 King William IV One Rupee (Calcutta Mint, "F" on neck variety) is a silver coin issued by the East India Company, struck in .917 fine silver, with a standard weight of 11.66 grams, diameter of approximately 30.5 mm, and a reeded edge. The "F" visible on the neck truncation of the King's bust is a recognized Calcutta Mint variety and is sought after by collectors. An XF (Extremely Fine) specimen typically retains sharp details in the portrait, lettering, and reverse wreath, showing only light wear on the highest points while maintaining much of its original design clarity and attractive silver patina.
