India to Issue New 100 Rupee Notes
 

The Reserve Bank of India (RBI) will shortly issue Rs 100 denomination
bank notes with `F` inset letter in both numbering panels in Mahatma
Gandhi Series - 2005 bearing the signature of D. Subbarao, Governor.

Except for the change in the inset letter, the design of these notes
to be issued now is similar in all respects to the bank notes in
Mahatma Gandhi Series - 2005, with additional / new security features
issued on Aug. 24, 2005.

All bank notes in the denomination of Rs 100 issued by the bank in the
past will continue to be legal tender.
