This is a British India One Rupee dated 1944, struck during the reign of King George VI. The example featured is described in uncirculated (UNC) condition.
One-rupee coins of the George VI series are cornerstone pieces for collectors of British India coinage, and the year and mint together decide how hard a given date is to locate. An uncirculated survivor — with full detail and unworn surfaces — is considerably scarcer than a coin that spent years in circulation.
As with all coins of this era, value rests on grade, mint and eye appeal rather than the date alone; a genuine UNC piece sits well above a cleaned or worn one. Coinbazzar lists verified British India one-rupee coins so you can match the exact year, mint and grade seen in the video.
