This looks like sheared mink to me. If it's in good condition - i.e., no bald patches, no storage or musty smells (or any other strong smells, for that matter), and if isn't shedding, you're off to a good start.
Check inside any pockets, often you'll find there's a label sewn in there.
I'm curious about the sweater parts, that kind of makes it more casual, and a little less 'valuable' for resale than if it were an actual coat, sewn onto leather or wool.
Figure out the condition. To me, it looks great in the photos. If it's in excellent condition - i.e., not stinky and not shedding, and not ripped or balding, I would try listing it for $175 on eBay, using the Buy It Now option. I've sold vintage furs that I've picked up at estate sales and thrift stores (mink and fox) in the $150-250 range, and it always went quickly.
If it doesn't sell in the next 4-6 weeks, I'd lower it to $125-150.
I just searched "Saks Furs" on eBay, and I think $175 for a jacket that's almost entirely genuinely fur would sell quickly. I would try and get the fur type ID'd, and list it as a "Genuine <furtype> Bomber Jacket".
FYI, if you do list it, put it on a mannekin or dressmaker form, or have someone model it for photos, in very good light. It will sell quicker.
Also, Lisa P is right - your friend isn't going to make a fortune on this, but it could bring it some nice spending money for him. It's hard to say, without really knowing what your secondhand clothing markets are. In Atlanta, I see secondhand furs in decent shape, ranging from $200-650, and they go FAST, usually within days. There's a lively community of women here who thrift and consign and love their luxury vintage stuff. If you're in a small town with a hot climate, such as Florida... it probably won't sell for nearly that.
