Below, you will see my pictures of the closeup. One will be the normal image and the other a “messy” color editing I did to show and compare where the similarities of the fakers mistakes were. The white line running in between the colors indicates the fold. The colors indicate where the bled ink touched with the rest of the bill, thus creating very light duplicate areas of the other side.
It is weird I got this from a bank, unnoticed (obviously) and I kept it for almost 4 years now in my collection. However, I don’t mind because it was free and I like it as a study piece. So there ya go. It is a FAke error note on a real federal reserve note.
