| Comments |
Applied Currency Concepts produced a series of novelty polymer notes themed around U.S. states and their historical figures — these are not legal tender and carry no monetary authority of any kind. Kit Carson's inclusion in the Colorado entry reflects his well-documented association with the region, particularly his years as a fur trapper and scout operating through the Rockies before his controversial later career as a Union Army officer during the Navajo Long Walk of 1864.
The QR code and barcode are functional — Applied Currency Concepts tied them to online content at time of issue, though link availability has been inconsistent over the years.
