I found this on a Rabbit years ago. Is it supposed to have any special significance? It's the only one I've ever seen.
Was that one in the middle of the grille lke the normal ones are. Might have been one of those Wolfsburg Bunnies or some such creature.
Actually, it was on the hatchback beside the "Volkswagen" script if I'm not mistaken. I think there was one on the dash too.
Cool. Try asking on the mk1 forum at vwvortex. Let us know if you find out anything.
Wonder if I could cast a couple of those in copper to go with my Fox build...
Want to sell it? 
I was thinking the same thing.
doesnt look factory to me... but thats just my .02
Its been bugging me and I can;t find anything about it lol.
Apparently it's from a 1977 Champagne edition Rabbit, according to several people over on vwvortex.
