I'm too old for this stuff. I'm still confused since they changed the grading to 70.

 

On $1s through $20s, there are 9,797 individual square roots that can be shown in 8 digits (from 1 to 95982109)

On $50s and $100s, there are 9,959 individual square roots that can be shown in 8 digits (from 1 to 99181681)

BTW, kudos to Karl B. for the comment. There is no wrong way to collect currency. Heck, if you wanted to save bills with the number 5 on them, you could.

 

I found a 11235800 serial number. Just missing the 13 on the end. Close...

 

I look for 11235813. That is the only serial I personally consider a Fibonacci note. That's what I call it. Had a close call the other day, but no cigar.

 

I'm with you...not that the OP's post is boring...but I would think in order to be considered a Fibonacci number, you'd have to have the previous numbers there....kinda how I understood it...either way...to each his own...

@paddyman98 the batman post was a nice add...lol

 

00000610 is still a cool serial regardless. Besides being a low number, it can also make a neat gift for someone born on June 10th. (6/10)
