I really love that idea as well, although the side with the boba helm seems to be missing something, or seems a bit plain. I think it would look cool if it had a ring around it that said "the dented helmet" in aurabseh, or something similar...just to add a bit more pizzazz. Also, about the coin weathering, Yes that would be cool, but these coins don't really weather!!! If they are made similarly to the 501st ones I have, they won't weather at all due to the hard epoxy enamel. I've carried mine in my pocket almost everyday for quite some time, along with loose change, nails, screws, and even the occasional spark plug. 
Mine still looks like brand new!!
Also, I ran this by a few of my fellow garrison members that we may be develpoing a coin in the near future. I had a pretty good response, and I really think we will have no trouble when it comes to getting rid of these or trading them for other challenge coins. I really hope this becomes a reality...pretty excited about it!!
