info on this coat please

can anyone tell me anything about this coat please? there is no makers label, just 2 emboided letters "D J" as in the photo, they are in the bottom right hand side (if you were wearing the coat) what its made of, era etc. thanks in advance.

 

Hi there, Pretty coat. It dates to the 50s and the fur is muskrat.

 

You're probably aware of this but the DJ would have been the owner's initials.
