Let's say few weeks and months pass and nothing happens.
Would you simply burn the words, give it to police, or maybe give it to some poor people?
There is always possible scenario of someone finding private keys of satoshi coins, any many other keys for inactive coins could be find by other people, so I don't see any difference with lost coins.
Should I be unable to locate the original owner after having exhausted all efforts to do so, within my capabilities....
* I don't know/trust anyone in my friend circle who can assist in such endeavor's, nor would I be confident enough undertaking many of the processes identified by the knowledgeable folk here who have offered their advice.
Wouldn't burn it or give to the police. Give it to some poor people? I have a number of charities that I know could use the coin better than I would. My main concern would be how to monetise the btc without having to give 30% to the tax man.
