Of all the language pins.....this one is the rarest. I have one as I am a CM who signs and when it was given to me I was warned that this is the pin that "disappears" off of CM costumes left at the store. I guard mine with my life.
I had one that I had found and I traded it back in February for an LE with all of the Pooh characters. I'm not even a Pooh fan but a mother and her daughters were admiring my lanyard and the daughter was taking a signing class and signed a poem about Donald Duck that she had learned. I truly thought this was the spirit of pin trading -- to meet people from other parts of the country and the world and find out a little about them. She was so happy that it made me happy.
Nat,
If it was on a separate pin, it was on one of the Sign language interpreters. If it was a part of the name tag it was a castmember who signs. I have seen them but I can't get them to trade.
