Yup, that is my coat!
It was from the 20s and had a large white rabbit fur collar which was removed, and the lining of white silk was replaced as well. The lining was fragile, although good when I sold it, but I knew it wouldn't put up with a lot of wear. The first time I saw that episode I remember thinking that the coat looked awfully familiar but because the collar had been removed I didn't recognize it at first. When I saw the rerun I realized. That coat sold for a hell of a lot of money too! I don't remember if I sold it to Patricia Field or not (costumer of the show), but I remember it went to New York, and I seem to recall it sold for about $650.00 (Those were the days!)
