A valuable serial number is either:
Counting (e.g. 12345678 or 87654321)
Repeater (e.g. 35353535)
Binary (e.g. 01001011)
Binary repeater: (e.g. 01010101)
Extremely low: (e.g. 00000033)
Sometimes birthdays / days of history too. (Like 07041776)
And they don't always have to be this extreme, a collector may buy a note with serial number 12345555.
Keep searching and good luck!
