1980 Lake Placid Olympics DDR OlympiaMannschaft pin

Found this pin recently, don't know much about it other than it's one I cannot find a duplicate of. It's a OlympiaMannschaft pin from the DDR (East Germany) for the Lake Placid Olympics and for the NOK (Nationales Olympische Komitee). I have not seen another pin like this if someone can point me in a direction of what the value of this would be or the history might be.
