Hello,
While we don't give appraisal values on the VFG, I can share that one sold last winter on Ebay for a very good price and had numerous bids. There seemed to be great interest in it. Men's vintage and antique fur coats are much scarcer than women's coats. Yours is handsome and looks to be in great shape. I love the lining, which can help to date it to the circa 1920s era. Good luck with that!
Also, donating furs to a good cause its always a good idea as well.
