My cousin John F Grismore was charged with possession of counterfeit currency and convicted. His case made it all the way to Tenth Circuit Court of Appeals. I'm not sure if he won his appeal or not. According to the website Justia, his case was:
United States of America, Plaintiff-appellee, v. John F. Grismore, Defendant-appellant, 546 F.2d 844 (10th Cir. 1976)
