Apayao is a sub-province in the sparsely settled northern part of Mountain Province. Probably because of the difficulty in supplying this remote area with provincial currency, it was decided to allow local currency to circulate on a limited basis. Two different issues are known.
The notes from the first issue were printed from hand-carved plates, and the amount (and quality) of ink used varied a bit. At points, India Ink was used, other times, thinned out house paint (or anything in between!). Due to this, it is possible to obtain notes of any denomination in which the printing was the same and yet the notes look very different... one way for a collector to form a highly specialized collection...
The second issue notes have many interesting varieties as well, due to differences in cutting and printing of the various sheets.
