I'll try to post some pictures of some of my more unique ones at some point.. My classiest/coolest ones are I believe from some sort of Swedish military uniform.. they are the traditional Swedish Royal logo royal blue background with 3 gold crowns. Hemispherically shaped, and if you look carefully there is what appears to be a coiled rope underneath the blue enamel.. hard to describe but VERY cool, and I have never seen another pair, searched Google, ebay everything.

I'm also into car related ones, my brother got me these for Christmas this year
