100 Rupees - Amended Plates Issue

The "Amended Plates" designation refers to modifications made to the original George VI-era plates following independence in 1947 — the most significant change being the removal of the royal cipher and the substitution of the new Indian government guarantee text. Rather than commission entirely new printing, the Reserve Bank authorized alterations to existing intaglio plates, a practical compromise that allowed note production to resume quickly while the new republic's institutions were still being established.

Signed examples are scarcer than raw print quantities suggest — many were withdrawn early as India moved toward the Lion Capital series. The issuing governor's signature on this series is a useful dating anchor for specialists.
