Unfortunately it seems to be about time to mark this coin as missing.
2011-08-17 it wasn't in the cache (where still listed) anymore, according to [url=http://coord.info/GL69V40X]this log[/url].
Hopefully some of the 2011-08-14 visitors could shed some light into this, but if not then please mark it as missing ASAP. (As you probably know, this i by no means permanent - if and when the coin hopefully pops up somewhere the finder simply 'grabs' it and the journey continues, just as before.)
