New Rs 10 notes with enhanced security features and an inset letter 'M' would be in circulation shortly, Reserve Bank said on Tuesday.
The new currency notes would have the letter 'M' in both the numbering panels, the bank said in a release.
The notes would also have enhanced security features, it added.
The design would be similar to other ten rupee notes in circulation at present except for the letter 'M' and additional security features. The new notes issued would be held legal tender along with other notes in circulation, the bank said.
Earlier, the Rs 10 notes were enhanced with special security features in April last year.
