I have a $1 one bill with a vertical stamp just to the right of the portrait of George Washington. It looks like some of it is gone, but I can read the last line. It says: ABA052001633 Anyone know what this is?
Pictures would help but by what your describing thats just the bills number out of the other thousands that were produced within that series.
A $1.00 bill serial number is only 8 numerals. So it can't be what you said It sounds like a stamp in ink done after the bill was printed.
No.. you're not understanding the question.. Do you have a $1.00 bill? Look at the serial number. It's only 8 digits With 1 letter before it and 1 letter after it. The person stated that there is something stamped on it and they don't know what it is.
Ok I understand now sorry but without a picture though this is what happens.The op just forgot and left
