I don't think that it's vicuna. If it were vicuna it would say so, plain and simple. There were be no need to be cute and call it something else. There would be no need to hint ("wink, wink") that it is vicuna. One cannot tell from the photos. It looks like an ordinary wool topcoat. It is worth more for your sentimental value than its value on eBay (perhaps $50). Good luck.
