Include or ignore?

So for the few readers out there of this blog, I want to pose these questions. On numerous occasions, I have seen coins, primarily pennies, embedded in the street, pavement or some hard surface that would make it impossible for me to retrieve it. Does this get included in the tally or do I just say "tough luck" and have to pass on it? In a related question, I have often seen a penny that is within someone's personal comfort zone, say on the subway or sitting down at a table and it would be rather odd for me to approach them to retrieve the penny. To this day, I haven't included either of these occurrences simply because I did not get the penny. Should I alter my policy?
