Mink? Stole like new, from no smoking home

The last pic is a close-up picture of the back it has subtle lines. There are no tags and my girlfriend is not sure when she bought this, but she said “it is probably mink”. However, I do not guarantee that it is mink. 19 inches from top of neckline and back to bottom of stole in center. No rips, tears or holes. From a no smoking home
