Hi, guys. Could someone please give me the term used to describe this serial number? Is this a binary, binary repeater, etc. This one seems to fall somewhere in the middle of the definitions I read on other sites. I'm a coin enthusiast so please forgive my ignorance. :)
Also, given that the bill is circulated with major folds in the center and on 2 of 4 corners, do notes like this one carry much of a premium? If this were a coin, I would grade it in the Fine-XF range. Thanks!
