150 Rupees Comptroller and Auditor General of India

The Comptroller and Auditor General of India was established under Article 148 of the Constitution, but the office itself traces directly to the Auditor General position created by the British under the Government of India Act of 1858. The 150th anniversary issue marks that founding moment rather than the constitutional entrenchment. At .500 fineness, this is a notably low-purity silver for a commemorative of this weight — a deliberate cost-control measure the Indian government mint applied across several issues of this period rather than an exception.
