Do you mean money with red numbers minted on, or handwritten on?

If you mean stamped or written on the money, then yes I have gotten a lot at work. Lots of them say to visit a website to track the bill, some have other dumb stuff on it. I am sure I have gotten some with numbers, but I don’t remember.

I’ll have to start paying more attention, because now I am curious to see.

I work at a gas station, I get a whole ton of twenties every day. Not a lot look pretty and have tape on them, writing, or other weird stains.

I had a money order with over $900 worth of twenties… what a nightmare

I should add, I looked more into this and some of that red/pink lettering could mean it’s a counterfeit.

I use a pen at work to check 20s, 50s, or 100s, so the ones I have gotten with writing were not fake per the pen.

Handwritten. Just written on by hand with a pen along the short edge of the reverse side. A string of numbers like, say, 10714021715128611.

Oh ok, then I think I have seen some? I don’t recall that long but I’ve seen number on money.

What does it mean?

Sounds serendipitous.

Have you heard of Where’s George?
It is a website for tracking dollar bills of any denomination. The bills are stamped with a mark saying something like:
“See where I’ve been. Go to Wheresgeorge.com”
“Registered at Wheresgeorge.com.”

It’s kind of a nerdy thing to do but it is fun to get an email with a hit from somewhere across the country.

@LuckyGuy, no, but that reminds me of the thing with books that was popular maybe 10 years ago: you put some kind of ID number in the front of a book and then left it to be found somewhere as a free book. The finder could look up the number and report finding it. Some books had quite a journey. I released quite a few books into the wild, including on a 4800-mile road trip, but I never found any.
