Would you all think this is a Keeper or sleeper? just thought it was cool being Binary? Or just being two numbers. The condition isn't great but not terrible. Okay, a little terrible.
It's only a dollar. I would certainly keep it because of the serial number. BTW a true binary is 0 and 1s, but yours is cool. Too bad the 6th digit wasn't a 4.
I'd personally keep it, and do keep these when I find them. It only costs a buck, and worst case keeping interesting notes is no different than squirreling away some emergency money. I had a co-worker think I was nutty for bringing home a set of common 1,000, 5,000, and 10,000 Yen notes from our trip to Japan instead of exchanging them back, like it was wasted money. Told him it was just like putting away a $10, $50, and $100 to save, but I get to enjoy them, so why not? Keep what you like!
I like the cool factor on the serial #. However, I completely concur with @SteveInTampa regarding your opinion of terrible condition. That note has seen better days, decades ago Sorry Mr Magooch, I give that a grade of terrible minus. Don't be too mad at me
It you are keeping the note for your own personal amusement, and not for monetary gain, the grade really does not matter.
