Travancore Rupee

The Travancore rupee was a type of currency issued by the State of Travancore, now mainly a part of Kerala in South India. The rupee was largely a newer currency in comparison to the older currencies of Kerala such as the "Fanams", "Achus", "Chuckrams" as well as the "Kasu" (or Cash). Its creation was probably intended for the increased trading with British India and the high-value transactions therein.
The Travancore Rupee was the highest denomination of currency issued for general circulation. The highest face value issued was the '1/2 rupee'. While there had been plans to introduce 'One Travancore Rupee', this was never done. The half-rupee and the quarter-rupee remained the highest values issued for circulation. The Travancore Rulapee was issued until 1946 CE (1121 M.E. or Malayalam Era), remaining in circulation till 1949. It was replaced by the Indian rupee following Travancore's accession into India.
Inscriptions.
Issues of the Travancore Rupee often had the names or insignia of the reigning monarch in English. The reverse features inscriptions in the native language of Malayalam as well as the royal insignia of Travancore. The inscriptions are largely a direct translation of the front of the coin. The year, when printed on the coins was based on the Malayalam calendar (and corresponding Malayalam Era - M.E.) which begins circa 825 CE. Therefore, the year of issue of the coin can be found by adding 825 to it.
Example - The year of issue of a coin showing 1000, will be 1825 C.E.(or A.D.). Therefore, the year of issue of the coin with the year 1116, as depicted in the images, will be 1940-41.
Unlike the Indian Rupee issued by the British and other princely States of India, the Travancore Rupee was subdivided into 7 Travancore Fanams. These "Fanams" were further sub-divided into 4 "Chakrams", each of 16 "Cash". 
We can see these sub-divisions in the following table -
As of the early 1900s, silver coins were issued in the denominations of Rupee and "Chakrams". Their various values included 2 chakrams, 4 chakrams, 1/4 rupee (7 chakrams) and 1/2 rupee (14 chakrams). The cash or "kashu" coins were largely copper coins. They were struck in values of 1 cash, 4 cash and 8 cash. The exchange rate with the British Indian rupee was set at 1 British Indian rupee = 28 chakram, 8 cash; equivalently, 1 Tranvancore rupee = 15 annas, 8.63 pies of a British Indian rupee.
