Is it legal to sell a shirt with an altered $100 bill design?

Question

I have designed a shirt featuring an altered version of a $100 bill, created by my graphics person, and I'm considering selling it. I've done some research that suggests it's safe to proceed but would like a second opinion to ensure there are no legal issues with using currency images in my design. Could you provide guidance on this?

You're smart to look into this before moving forward. Using U.S. currency designs, even altered ones, comes with specific legal guidelines. The U.S. government actually allows reproductions of currency under certain conditions, but those rules are strict. 
 
According to the U.S. Bureau of Engraving and Printing, any image of U.S. currency must be less than three-fourths or more than one and one-half times the size of the actual bill. It also has to be used in a way that can’t be mistaken for real money, and only one side of the bill can be shown. So if your shirt design follows those size rules, alters the image clearly, and doesn't promote counterfeiting or deception, it’s generally considered okay. 
 
That said, it’s always a good idea to make sure your design can’t be interpreted as disrespectful or misleading. You might also want to check for any copyright elements, like newer design features, though currency itself isn’t copyrighted. If there’s any doubt, it never hurts to run your design past someone with experience in intellectual property law. But overall, if you're following the legal guidelines, you’re likely in the clear.
