In fulfillment of its mandate to maintain public confidence in the Belize currency, the Central Bank of Belize issues currency notes with enhanced security features. In May 1990, the Central Bank of Belize put into circulation a new family of Belize currency notes consisting of seven denominations. This family captured the rich variety of Belizean wild life, national culture and historic sites and highlighted some of the rare and endangered species of the birds and animals of Belize. Although the 1990 issue of currency notes is legal tender, these notes are outmoded (Source: Bank of Belize).
