from http://www.jfcampbell.us/india/george5/george5.htm : The Rupee was minted in both Calcutta and Bombay. There is no mint mark for Calcutta. The Bombay issues, like this one, have a small dot on the reverse under the ornate near the bottom of the coin. 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.
