Year for Egyptian banknotes

Can someone help me by telling me which exact year is each banknote?
Thank you

They used to date them in suchba complicated way. I believe that the first and last digit are the year and the remaining middle digits are the month and day.

11-19-97 may be the top note.

The last note might be 4-4-89.

5-8-90 or 8-5-90 could be the middle note...i hope someone better can come along and correct me. Im desperately trying to remember how i dated my notes successfully. No doubt when Numista does banknotes we will have a document to assist.

Does not make any sense why to split the year, I think it's just the serial number.

Well...i collect them...so yeah...im not looking at the serial number either. I am looking at the series of digits that appear in the lower left quadrant. So...yeah.

YDDMMY is the pattern. I was right. Egypt used to date their notes in this manner. My dating is correct.

Yes these older Egyptian notes use the date format of Y/DD/MM/Y. So the first and last digit indicate the year, the middle ones the day and month. So the dates on your notes are (from left to right):

9/19/11/7 = November 19th, 1997
9/05/07/0 = July 5th, 1990
8/04/04/9 = April 4th, 1989

It also took a while for me to understand this system!
