The Reserve Bank on Friday said it will soon issue new notes of Rs 100 and Rs 10 denominations in the existing series named after Mahatma Gandhi.

While the Rs 100 denomination notes will have the inset letter ‘L' in both numbering panels, the Rs 10 notes will have the inset letter ‘B', the RBI said in separate statements.

The notes will have the signature of RBI Governor, Dr D. Subbarao, on one side and the year 2011 printed on the other.
