100 Dollars - State of Colorado

This is not a federal instrument. Colorado's recreational cannabis industry, operating legally under state law since 2012 but still denied access to federally insured banking under the Controlled Substances Act, forced many dispensaries into near-total cash dependency. A handful of state-chartered financial cooperatives and legal workarounds emerged, but the structural problem never fully resolved. Notes denominated in "State of Colorado" dollars are not legal tender in any recognized sense — they are scrip instruments or novelty issues, and their legal standing under federal law is questionable at best.

Without a confirmed issuing authority and specific series data, little more can be responsibly said.
