Comment: So the legal premise

(See in situ)

So the legal premise

is that we'd be waiting for the coinage to become not-currency by legislative fiat. Then we could trade it as bulk metal. As scrap. But in all likelihood the gubmint will order it's surrender for trade in whatever e-bucks thing they'll conjure up.

As far as copper goes we can just melt it down and cast it into all kinds of useful things like...bullets but nickels? If memory serves they are like 70% copper which is a pretty common alloy and I know there's a market for it but I wonder where exactly that is or how to access it. Scrap dealers won't want to take it in coin or ingot form at it's minted alloy. However it would be easy to offset that alloy with more scrap copper. And casting sculpture or other ornaments is a possibility.

Be brave, be brave, the Myan pilot needs no aeroplane.
