The Challenger SE emblems originally had a clear, smooth coating over the red white and blue. The texturing or pebbling in the finish found on most remaining original examples occured as a result of exposure to the elements.

I had a set of what must have been very early NOS pieces that had this clear untextured finish. Later NOS and reproduction emblems do not have the clear coating at all.

A while back I enquired about restoring a set of original emblems at www.emblemagic.com. They quoted a price of I believe $200-$300 to restore the emblems including paint and the clear coating over the red white and blue. Since I had found the NOS emblems I didn't follow through so I can't comment on what the finished pieces would look like.
