H&C mold chips with the same inlay are listed as UFC, with a notation "Ordered for Free Trade Zone in North Korea, but never delivered".
These are plain mold, 47mm and 50mm, higher denominations, but identical inlays as the H&C chips. Are they UFC's or North Korea?? Were they made as novelties?? Any information would be much appreciated. Thanks, Doug in Kingman, Az.
