I'm a pizza delivery driver atm, so I come across a decent amount of bills. Recently I got a well circulated $1 bill. However, on the back I noticed there is a red marking. It's pretty hard to read the smaller text, but I've made out the Latin phrase "E Pluribus Unum" which is found elsewhere in the Bill design and "federal" followed by some text I can't quite read.
I've never seen this on a Bill before. Has anyone else? Is it worth holding on to it? Is there any sort of extra value?
Also, I'm case anyone's wondering, it's a series 2017.
