I would like to request adding the demonetization date for the entire American-era Philippine coins (which are coins dated 1903 to 1945) to be March 31, 1979 as it is confirmed by a catalog admin and the date information came from a primary source which is essentially from the BSP (formerly the Central Bank) themselves.
The following coins below are the ones I request adding the demonetization date for.
N#4354 - Half Centavo (1903-1908)
N#6696 - One Centavo (1903-1936)
N#6378 - One Centavo (1937-1944)
N#4353 - Five Centavos (1903-1928)
N#16639 - Five Centavos (1930-1935)
N#16638 - Five Centavos (1937-1941)
N#4711 - Five Centavos (1944-1945)
N#15871 - Ten Centavos (1903-1906)
N#4352 - Ten Centavos (1907-1935)
N#4712 - Ten Centavos (1937-1945)
N#15872 - Twenty Centavos (1903-1906)
N#4351 - Twenty Centavos (1907-1929)
N#7513 - Twenty Centavos (1937-1945)
N#15873 - Fifty Centavos (1903-1906)
N#4350 - Fifty Centavos (1907-1921)
N#15858 - Fifty Centavos (1944-1945)
N#4349 - One Peso (1903-1906)
The One Peso small type from 1907 to 1912 already has the demonetization date of March 31, 1979 validated by a catalog admin and added into the catalog.
A few extras as they are constituted as coins from the year 1945 and below or Mule errors.
N#21142 - Five Centavos 1918 Mule
N#21143 - Twenty Centavos 1928 Mule
N#21145 - One Peso 1936 Roosevelt and Quezon
N#21144 - 50 Centavos 1936 Commonwealth
