Bank can't legally refuse. If it can clearly be reissued, there's no problem. Mainly as long as it's not so marked to be illegible or to change the denomination.
A separate law makes it illegal to use US currency for advertising (like writing "Eat at Joe's" on a bill).
What is the legality? I had a Trump lives here and used it on several $20....can a bank refuse?
