I am not a strike collector, but I do have a few. Two in particular that I have questions about are shown below. The one with the snake and the chinese inscription below it (right), I am told is special and in limited quantity. How I aquired them is that I bought them for a friend who, just before I got them, he had aquired them as well, so I kept them.

What are they worth, about? What is the story behind the one with the inscription (right)? That one I paid ~$100 for, the other I don't remember what I paid. Thanks
