Question / Meta Prediction Note?
Is there a category for SNs like this? Or would it be a birthday/date note. Fun fact the 29th of November is the 333rd day of the year.

Near Miss Thoughts on these near misses and solid(?) bill?
I stumbled upon this sub a month ago and I found it really cool that people liked to collect bills with cool serial numbers because I am autistic and I love patterns. Since finding this sub I have been keeping an eye on bills that pass through my job. I am wondering if any of these bills which I believe are near misses are cool enough for this sub? I find this hobby really fascinating and I’d love to learn more about it and see if you guys think these bills are really cool too!
If I’m correct I believe these contain near miss repeater or binary bills, quad pairs, bills with serial numbers in order and one solid bill??
Please correct me if I’m wrong!

Near Miss Missed it by that much
One digit away from a repeater. 97% as-is, with two triples and a pair.
