Yep, that's pretty fancy! Binary radar, but you'll have to wait on a value from someone else. I don't suppose you found it back on the 2nd of the month...?
Nice find. Welcome to CT Dave. Many call these birthday notes. A person born on 02-02-2020 would probably pay a premium for this bill, and the others. $100 in $20s might be a bit rich to hang on to, but you might be able to make a little money on them by selling them.
Meow is always tempted to keep crisp $100 bills when they come along. But then Meow thinks of all Fancy Feast, Meow Mix, and collectables it can buy, and eventually will spend it.
Much like cannabis or opium poppies, eh? (Was going to add Psilocybe, but mushrooms aren't plants...)
Separate thing at the same level as animal or plant. Actually a bit closer to animals than plants phylogenetically, as I understand it. It's just animal-chauvinism that makes us think of them as plants...
