Emblems

Sorry to post 2 forums within the 5 minutes I did, but I was just thinking. I have a cup of "extra parts" which I'm sure you all have.. I have like 2 sets of the "O.P.E.L. G.T." for the rear panel, a Blitz emblem for the front, I think a GM emblem, a 1900 Emblem, and another emblem that just says "OPEL" on it in kinda stretched out looking letters..maybe goes to the drivers side in front of the door. Anyway, how much are these worth, if anything?
