According to a press release dated 12 October 2015, the Banco Central de Nicaragua has unveiled the designs of its new note family which it introduced on 26 October 2015. All of the denominations are printed on polymer substrate, except for the 500-córdoba note (B511) which is printed on cotton paper substrate. Existing notes will continue to circulate in parallel and will be withdrawn as they deteriorate.
