After my visit here today, I can witness that this GC really is not present in GC5M1ZW. It is obvious this GeoCoin has been lost for a year and half. Nobody has logged even Discovered It since it was dropped here in May 2016. Nine months later Ajma for the first reported that it was missing.
Because now the trackable is elsewhere, but absolutely not here, that is why I ask you, Easy Ed, for marking it as "missing", i.e. to put it out from the cache virtually, too. There is no reason to let it here further. (One of the GC and TB cemeteries not far away, where GC can "rest in peace" forever, is e.g. cache GC1A8K2).
