Leigh Ann -
It is the same shape as the pledge pin but black enamel on gold. Here is a pic of all the npc badges -

we are in the bottom row second one from the left.
I am going to send an email to national on this one - I didn't think we engraved the backs but if so, they will know exactly whose butt to kick for selling their badge. It's in reserve and I am guessing it's one of those ones w/ the pearls & rubies - too rich for my blood.
Thanks for finding it!
