i got this as change the other day...just a normal 20. the signature of the secretary of the treasury is scrambled, or something. i believe it to be a misprint, maybe? lol. tell me what you think.
Pending that that was done while it was being printed and not after it left the bep it will be worth some money. It is called an Ink Smear. This is the first time I have seen it on a signature. Go have it looked at by a professional. They can tell you what it is worth.
A minor ink smear (such as yours) increases a n0te's worth by $20 over face in VF; or $50 in UNC. per the 5th edition (2016) of The Official Red Book --US Paper Money
