Placed this in a cache where it might take a while before the next geocacher comes to pick it up. D4.5/T5 is the rating of this geocache. But in this very nice mysterycache in Vienna this coin is very safe from muggles. Without climbing gear and very good knowledge on how to use it no-one will reach the geocache. The last geocacher here was more then 6 months ago. So relax and sit back. Someone might climb there tomorrow but it could also take several months...
