CalMeacham’s two posts mention not seeing the medallion in the movie. Does everyone else remember the medallion in the movie?
This link has the reason for him not wearing the medallion all the time…
“Dracula at home vs. in society. His home look is only slightly less formal, with subtle stripes on his tie and waistcoat, the added medallion around his neck, and his collar wings worn over the tie.”
Scroll until you see the two side-by-side pictures of Dracula.
