It's very interesting that he asked the media to send coins to one of Satoshi's Bitcoin addresses, and that he would return them. All of Satoshi's original coins are Pay-to-Public-Key, whereas the BBC's money was sent Pay-to-Public-Key-Hash (P2PKH). This means that Craig would have to present a signature along with a public key that just has the same hash as the Satoshi public key, not a signature for Satoshi's public key itself. I think he is banking on finding another key with the same hash, as a final desperate attempt to forge his identity.
