I see no advantage to hoarding CuNi nickels. What are they? Cu bullion coins that are .750 fine, or Ni bullion coins that are .250 fine..? If and when the melt ban gets lifted you will NEVER get the theoretical MV on these things. The cost to separate the 2 metals is just to cost prohibitive. They are a CuNi alloy. As somebody already mentioned, the refiners will amend the alloy to the more common 80/20 or 70/30 alloy. You will get scrap CuNi prices. Canadian .999 Ni nickels are the way to go if you want to invest in Ni. Or any of the easily available foreign Ni coins.
