The football-shaped one has a small chip of white missing after the "C." The round one on the license plate has a bit of dimpling in the black. Both are cloisonne (hope I spelled that right).
Each appears to list for more than $100, probably about $250 for the pair. ( http://germancarbadge.com/badge-award.html ) I looked in my old e-mails to see what I sent Paul -- and couldn't find it -- but I'm sure I got a slightly better deal; I bought four at one time or something like that.
I don't know what demand is for these guys, but it seems to me that $150 for the pair -- as they are and with their mounting materials -- is a good place to start. I'm sure you could make a nice penny on turnaround if you wanted to.
(Unless somebody wants to split the set by offering me a Corpse badge in exchange for one of them? Hmmm?)
