This coin is struck on the standard of Mughal Coinage. Tipu Sultan ascended the throne on 29^th December 1782. Sultan adopted two types of nomenclature for the twelve months of the year. The first, in which the names follow the "Abjad" system was in use during the first four years of the reign and coins were struck with AH date pattern. While the second which follows the "Abtath" system came into force in the fifth regnal year, along with the Mauludi system of dating the coins.

We encounter only gold pagoda and copper paisa from Tipu Sultan's first year of reign (AH 1197) and no silver coins were reported except for a half rupee dated 1200 AH. This half rupee hitherto unlisted is a rarity.

One of the highest rarity of Tipu Sultan half rupee and being offered for the first time in any auction house!
