Whew... I just spent the last two hours reading/looking at all the different ways to store/display geocoins. Wifey's on the other computer looking at lakefront property. I think this is a bit cheaper, but maybe not for some.
Funny how it grows on you. I love finding geocoins in a cache or discovering them in someone's hand. Then I saw this one coin that I thought would be great to carry around and let other geocachers discover. Of course it was no longer made, so I had to trade for it (thanks drneal). That meant buying traders. In the process I found other coins that were "keepers". So now I'm looking for ways to display my keepers, which are currently in a binder with plastic sleeves. No one's allowed to pick it up except me, for fear of them all falling out. My traders fill a small priority mail box. Nine stacks fill it tightly, but it's a bit difficult to look for a particular one, although it allows me to rediscover them on a regular basis.
Thanks for all the great ideas. Each idea seems to have its advantages and disadvantages. I'll let you know what I decide. Also interesting reading about the few misconceptions about how and why we have these travelers.
