I found this dollar today and it looks like the "e" on the back of the dollar bled through a little or something? You can see weird dots... is this an error or anything special?
Also look at the edges... theyre misaligned or something. And under washingtons lip there is bleed through I think too from the other side
Unfortunately neither of the issues you described are errors. The bleed through effect is common, unless it's very severe. As far as the alignment, it's only an error if the next note is visible.
none is an error whats so ever, its just ink splash from the rolling process. AND the dollar bill on the bottom is the outer sheet cut of the 100 bills. the one on top is center. they all have the same size its just how they get cut, years differ.
