HK-869, Colorado 'Century of Progress' Dollar, Type III.  Created and sold to defer the cost of Colorado's representation at the 1933/34 CoP at Chicago.  Only 2,000 struck, with a considerable number melted, so significantly scarcer than the Type IV.  As these were apparently all sold in the State rather than at the event, not listed in Shevlin's U. S. Exposition reference.  A nice original specimen, just some very light wear however no damage from its apparent short use as a pocket piece.  Probably more valuable from the historic perspective as such, as most that survived did so in 'new' condition.
