What is 1 ruppee coin?

As an AI language model, I don't have current information to provide about a 1 rupee coin. However, historically, the 1 rupee coin was first issued in India in 1950, after India became a republic. The 1 rupee coin has undergone several changes over the years in terms of composition, design, and size. Currently, the 1 rupee coin is made of ferritic stainless steel and measures 20mm in diameter and weighs 3.79 grams. On the obverse side of the coin, there is an image of the Lion Capital of Ashoka and the denomination "1" written in the international language of numerals. On the reverse side, the word "India" is written in English and Hindi, with the year of minting and a floral wreath surrounding it.
