Melting old pennies

Nickel. It’s spelled nickel.

Carry on.

So now he has two million nickels lying around that he can legally hoard, but not legally melt down. Basically, he can’t do anything with it - and while he’s hoarding them, the storage costs (and the foregone interes or dividends that he could have gained investing the $100,000 in a more conventional manner) are ongoing costs. What’s the point? Melting them down eventually anway, even though it’s illegal? Waiting for the ban on defacing currency to be lifted? Doesn’t sound like a very solid business model to me.
