I too am concerned about loosing my coins. Many of the caches that list a coin or TB don't have anything inside when you get there. I have heard of people keeping the coins and just having others discover them. That is not right. If you own the coin, you can do whatever you want with it, but not if it belongs to someone else. I recently earned some AGT coins. I refuse to lose them since I had to work for them. I am borrowing an idea that I found in other caches. I took digital photos of the front and reverse of the coin, printed them in high quality color, laminated them, and am going to put that in the caches to travel. Some have complained that they are denied the chance to see the coin. My photos are just as good if not better b/c they are slightly larger and easier to see. They are just not 3-D or heavy. Again, this was not my original idea, but I am definitely doing this instead of losing my coins. I hope my coins can complete their goal. I love to get coins and TB's at caches and move them on to a new one and I am sure others feel the same. I have been caching for about 1 month now and have 64 finds. I hope to place my first cache soon. Happy Caching to all.
