Please help identifying these fur coats

[Stephanie butterman]

Hi
I have inherited two fur coats and do not know anything about them. Any help you can give is appreciated. Type of fur and company.
One is full length without any label. It is well made and very heavy. Outer is brown leather and inner is fur.
The other is a jacket with MikB label which I can’t find any info on. The fur look like short hair under coat with long hairs. Not super soft. Heavy for size. Not sure how to tell if real.
Thank you so much

Hi there, the inside of the first coat is sheep and it looks like a belted trench style with bucket pockets. I would date it to the 70s.
The jacket is horizontally let out pastel brown mink and I would date it to the 60s.
The label looks more like a monogram which would have been a name or initials the wearer chose.
