We never understood why some geocachers feel the need to discover coins they have never seen for real. Just move them and you'll get the icon and everybody is happy!
But in this case, we think those cachers who are too lazy to move coins are not able to move this coin, since we put it in cache that is not easy to open 😉. But we dare the next cacher who discovers this coin without ever having seen it, to visit cache GC3KRZB and try to log it!
Good luck on your journey!
