ok I think this birthday thing is my fault. I started this crazy search 2 years ago. Yes you all know the date. May 21 2005
I regard the birthyear note or any special day note as within the 7 numbers you can have that special date.
eg. May 21 2005
5212005 Month/day/year
2152005 day month/year
2005521 year month day
2005215 year day month
really streaching it is
2120055
5200521
A birth note is
0002005
So would you regard 2005000 as a birth note?
The value is to have anyone who has a special date to have that note. It works as a cheap Christmas present or gift to mark that special day. Maybe not real numismatic value but a lot of value to the person that recieves it.
By the way, does anyone have any true birth notes example: 1987,1924 etc.etc.
