Culion Leper Colony is located on Culion Island, 20 miles long and 10 miles wide. It is located a short distance north of Palawan. Culions´ notes where issued first without presidential authority (more common), and later with presidential authority (rarer). This authority designation was printed on the back of the notes, and all notes had the Bureau of Health stamping in blue.  None of the 1, 5 or 20 Peso notes had the presidential authority clause on the reverse.

These notes were printed on thin paper which was coated with paraffin.

Recently a hoard of these notes was discovered, making them much more obtainable.  I have conferred with Neil Schafer, and he believes this hoard to contain authentic notes.
