My collection is more on silver coin and straits settlements coin. One of them is this one rupee British India King George V 1918 silver coin. I bought this coin this year in penang. I don't know much about this coin until I Google it recently. This coin history making them more interesting.
This indian rupee is also called "pig rupee". Why? The first year of issue (1911) has an elephant on the Kings robe that was considered to resemble a pig, thus the variety is known as the "pig rupee" (Type I). This variant is also on the 1/2 Rupee, the 1/4 Rupee, the 2 Annas and the 1/4 Anna coins. The elephant figure was redesigned (Type II) and this design was used on all issues starting in 1912.
Mine is aType II with a new design of elephant and mint in bombay. The Rupee was minted in both Calcutta and Bombay. There is no mint mark for Calcutta. The Bombay issues have a small dot on the reverse under the ornate near the bottom of the coin (see illustration).
