I have been leaving hand made "monkeys fist" key chains for the past year. My uncle, who inspired a lot of my love for outdoors, taught me to make them 25 years ago on a camping trip. But I am toying with the idea of custom button pins. I have found a few and I like to put them on my backpack. Seems like something functional or decorative is the way to go. I usually only trade out foreign coins, but I try and leave my sig stuff, if the container is big enough (and nice enough to keep water and critters out)
