Gosh, to hear this cacher is kind of disturbing. We cache for fun, never looking at contents before we go for it. Caching for us is doing something with our boys. It is exercise and most of all it is the love of the hunt. If you are seeking coins...etc look at purchasing them. Most coins in caches are for moving along not for keeping unless it is unactivated.
Not sure why this cacher is so upset. Caches are found by muggles who don't know what they are and some are lost forever...never mind just a coin. You are looking for the wrong reasons for caching.
