The coins minted by Liberty Reserve were in fact clearly labeled with their brand and not at all likely to be mistaken for U.S. currency. Their web site, libertydollar.org, was imprinted on the back, and there was no claim of any official endorsement from the Federal Reserve. All U.S. coins in general circulation have "United States of America" around the perimeter on the reverse side, which was not present in the Liberty Dollar design. The Latin phrase "E Pluribus Unum" was also omitted. The obverse designs could be considered vaguely similar, in the sense that most coins share some similar elements, but that's just the word "liberty", the year, and a stylized profile of the Statue of Liberty (which is technically French)—not even a profile that could be mistaken for a U.S. president. If that's considered enough to cause confusion then the Federal Reserve is at least equally at fault for making their obverse designs so generic.
