Here are some of the closer detail of the error found.
Notice how the border of the other side of the note appears(dark like spots) partially on this side.
Here is the closer view in middle part of the note where the words TEN PESOS shows partially as well.
Also the lower part having almost the same occurrence of the upper part of the note.
I've decided to keep this note since to me it is some sort of a prize. It shows that even with the modern equipment in producing paper money during that time, still in rare cases, such mistakes appear. It is good to see something like this came out, otherwise according to Mr. Coolpit error notes are not really qualified for circulation and was usually destroyed as a defective currency.
I would like to say many thanks to my Braingle friends who decide to drop by and visited. For those others who are curious to what I'm talking about you can visit http://www.braingle.com/ and perhaps that would spark some interest as well. For me, it is a site where one can interact and make friends from different parts of the world.
