According to a Banco Central del Uruguay (BCU) press release dated 11 January 2011, Presidente Mario Bergara presented a new set of coins with designs based on native animals, and announced that a new series of notes began circulating. The notes are unique for Uruguay in that they are the first to carry the signature of a woman, Secretaria General Elizabeth Sonia Oria.
The only note depicted in the press release is the 100-pesos uruguayos (US$5) denomination, which is like B547f, but with new signatures (Oria/Bergara), new date (2011), series F, and new printer imprint (DE LA RUE).
