I'm a small rock, mineral and fossil collector in Missouri. I have extras of local rocks, minerals and fossils that I would like to trade with other rockhounds. We can trade a box full of whatever you want to put in it. I've traded with several other rockhounds and have never been disappointed in a trade. It's a great way to get rid of extras and at the same time get new pieces. let me know if your interested. keep4u@yahoo.com
