Mink, muskrat or beaver?

[Biona]

I thought this was mink...but now I'm now quite so sure. It has a striped lighter color under layer and maybe not quite as soft as mink I've felt in the past. I bought it along with a Lilli Ann mohair coat. I assume they're both from the 60's?
Thank you in advance for any help!

Hi Biona,

Can you please show me a front view of the coat and also a flat open shot of the lining?

Thank you.
