I have a 1 Guarani Paraguay note that looks different from some of the pics I have seen of it. The front has the man that all versions of the note I've seen have, but the serial numbers are both on the bottom on my note. Other versions I have seen have one serial number on the bottom and one on the top, on opposite ends of the note. The back of the versions of the note I've seen with serial numbers both on the bottom as mine are have a building photographed at a slight angle. Mine has the other back I have seen with the serial numbers on the top and bottom at opposite ends of the note, which is the building photographed straight on. Is this a possible error? Rare enough for a premium?
