The Reserve Bank (RBI) on Sunday said it will issue new currency notes of Rs20 and Rs50 denominations with numerals in ascending size in the number panels and without intaglio printing. The old notes of Rs20 and Rs50 will remain legal tender. “The RBI will shortly issue Rs20 denomination banknotes in the Mahatma Gandhi Series-2005, with inset letter ‘l’ in both the number panels, bearing signature of Urjit R Patel, Governor, Reserve Bank of India, and the year of printing ‘2016’ printed on the reverse of the banknote,” the RBI said in a statement.
