If you're thinking of something along the lines of your state seal encircled by a buckle and strap, like clan crest badges, remember the buckle and strap mean that the wearer is declaring his/her allegiance to the owner of the crest. With a clan badge, this means that when I wear my Lockhart badge, I'm declaring my loyalty to my Chief. If I were to wear the North Carolina state seal encircled with a strap and buckle, it would mean that I'm declaring my allegiance to the owner of the state seal, which some people might say was the governor, others might say is the state legislature (which we call the General Assembly), and others could say is the people of my state. You can see how that could lead to all sorts of "interesting" discussions. If I were to wear a state seal pin without the buckle and strap, it might be a good conversation starter, but to me it just doesn't look right without the buckle and strap. Maybe I've seen too many clan badges and now my vision is warped.
