Finance Minister Arun Jaitley on Tuesday released a commemorative silver coin to mark the 300th martyrdom day of Sikh General Banda Singh Bahadur. Jaitley said Bahadur (1670-1716) was a great leader, who fought the Mughals and established the first sovereign Sikh state. Notably, Guru Gobind Singh had conferred the title 'Bahadur' and appointed Banda Singh his deputy and military lieutenant.
