One dollar bill 1963 series a with a misprint of a name Tim o'malley on the bach of it what is it worth?

It's hardly a "misprint" - after all, how could a person's entire name end up on one bill when they're printed in huge sheets of multiple bills? Someone used a stamp to put their own name or that of a friend on the bill, that's all.

P.S.: Bach was a famous German composer ... the bill has a back, LOL!
