I have a collection of 200 peso bills.
They are quite rare and that is why whenever I get a hold of one I would keep it and not spend it unless deemed necessary. Even my family supports this obsession of mine and that is why I have acquired such a collection.
so whenever you ask yourself why have you not seen one for a long time, it is maybe because someone out there hoards them like crazy. ( and that's me <happy noises> )
