The Oglala Sioux Tribe issues its own currency under the sovereign authority recognized through federal trust relationships — a practice with genuine legal standing but almost no circulation in practice. These brass dollars function largely as a political assertion rather than a transactional medium, with the Pine Ridge Reservation's cash economy running almost entirely on U.S. federal currency. Tribal-issued coinage of this kind occupies a genuinely ambiguous legal space that the U.S. Treasury has never formally moved to suppress.
