Front: Mahatma Gandhi in three-quarter profile at the right, the familiar smiling 1946 study that has fronted every Indian note since 1996. Left of him, the Reserve Bank seal with its palm and tiger, the intaglio 100 and एक सौ रुपये stacked in the centre, and the promise to pay in Hindi and English above Raghuram G. Rajan's signature. The Lion Capital of Ashoka sits low at the left, beside the blank watermark panel, with red serials at upper right and lower left.
Back: A long Himalayan panorama fills the centre panel — snow ridges and shadowed foothills framed by a scalloped arch, engraved in slate blue over pale green guilloche. At the left, the denomination in fifteen official languages boxed in a narrow panel; ₹100 in both upper corners, 100 एक सौ रुपये and ONE HUNDRED RUPEES along the foot, with the year 2015 printed centrally below.
The Mahatma Gandhi Series hundred ran from 1996, this later printing carrying the ₹ symbol adopted in 2010. Unaffected by the November 2016 withdrawal of the 500 and 1000, it stayed in daily use until the lavender Mahatma Gandhi (New) Series 100, with Rani ki Vav on the reverse, arrived in 2018 and gradually displaced it.
