Vintage Neiman Marcus Mink Coat

This is a late 70s/early 80s vintage mink coat. It is dark brown, almost black and knee length. I would say it’s is a size 10/12… no size is in it. It does have an original embroidery from my great aunt in the lining. It has been appraised for $2500-$3500 by a fur shop. It does need a cleaning and a bit of maintenance. Please ask any questions you have and I’ll do my best to get answers!
