Serial numbers on specimens

Hi, I've noticed on several specimens that along with the classic "000000000" there is another serial number. Concrete example here:

http://www.ebay.com/itm/Vietnam-100...0392048920?pt=Paper_Money&hash=item439cb70518

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.

Thanks

on US specimen notes i have seen the serial #12345678 or #23456789

here is a site that shows a bunch of specimen US currency http://currencyforums.net/view_topic.php?id=116&forum_id=2

 

One issue you have is that production of specimen notes is not some sort of global agreement as far as numbering, quantity, usage, etc. So your questions must be scoped within a particular country, and you need to find a specialist, or at least a specialized catalog, for that particular country which may have the information you need. So in this case, you're looking for specialized information about issuance of specimens from Vietnam, but once you find that answer, it says nothing about serial numbers and quantities of specimens from Laos or Phillipines.

Not sure I understand it all. For example, if Vietnam produces 50,000 specimens to be sent to other countries, they overprint the specimens themselves(or is it the foreign countries who do that?) with the word Specimen and/or Tiên Mẫu and also with the serial number. Then they would send the whole 50,000 of these specimens to banks of foreign countries which would have a use for them. Say that I'm able to get the information that 50,000 were printed, why should I have an issue ? Please correct me if I'm wrong...

 

Dave M probably feels you collect notes from various countries. So what one country may do on thier specimens will have no bearing on another countrys' notes. You will have to research every country independently. No single rule applies.

 

Oh, clears it, thanks.

 

Thanks yes, that's what I meant.

Cool, I guess you don't have different serial numbers on your notes in the US as far as I can see, it's either 00000000, 12345678 or 23456789 along with different prefixes and suffixes... Are those the proof printings at the beginning ?

 

At least for non-federal banknote printing in the U.S., all the genuine printer's specimens I've seen use multiple zeros or sometimes no serial number at all. I've seen "specimen" stocks/bonds with various numbers, but these are just rubber stamped after-market and don't really qualify.
