There are a limited number of bitcoins and Satoshi started out as a monopolist of them... so Coase expects them to get sold at the marginal cost?

There are a limited number of iPhones....?

Do either of those examples shed light on where Coase went wrong that agree or disagree with the authors?

bitcoins are sold at marginal cost, that's how much miners are willing to spend to mine them.
