Today I got this bill from Petsmart, it was the first non-star note I thought I'd keep. Just wanted to share :smile
On this website I found in an old thread (www.coolnumbers.com) that someone used for fancy serials, I entered it in and got a "Universal coolness index"(lol) of 99.29 out of 100. Pretty good lol.
pretty cool serials on both of the notes. I don't collect fancy serials, but I owuld definitely think of keeping both of these if I got them for face value!
I posted this back in December For coolness factor: 98.8% 45400454 is a palindrome! Only 0.010% of 8-digit numbers are palindromes. 45400454 contains a 4-of-a-kind and 2 pairs. Only 0.15% of 8-digit numbers have this combination. 45400454 has 3 unique digits. In 0.71% of 8-digit numbers, there are 3 or fewer unique digits. 45400454's digits sum to 26. In 12% of 8-digit numbers, the digits sum to at most 26.
