Hi, I've noticed on several specimens that along with the classic "000000000" there is another serial number. Concrete example here:
On this example, am I safe assuming that AA 0006891 indicates this is the 6891st specimen printed of that kind(2004-2006 100,000 dong specimen note)?
And if this is the case, the lower the number, the higher the value?
How can I know how many specimens of a certain kind were printed ? I would like to know if a number is relatively low.
