The "Banco Central de Costa Rica" began issuing paper money in 1950, with notes for 5, 10, 20, 50 and 100 colones. The first notes were provisional issues produced from Banco Nacional notes (unsigned and undated). The Central Bank printed on them the corresponding signatures and dates, and the legend "BANCO CENTRAL DE COSTA RICA" over "BANCO NACIONAL DE COSTA RICA". Regular issues of notes began in 1951, but a second provisional issue of 2 colon notes was made in 1967. 1000 colon notes were added in 1958, followed by 500 colones in 1973, 5000 colones in 1992, and 2000 and 10,000 colones in 1997.
