The easiest places to sell a fur coat are at high-quality vintage clothing stores or resale furriers. Selling them online at sites such as eBay.com or Etsy.com is also possible, but this requires more effort.
Vintage clothing stores and furriers tend to be located in larger cities and also may not take all fur coats. They only take those they think they can resell. Online sites may be more effective for worn or unusual coats or for people in rural areas. They have the benefit of getting the coat out to a wider audience. Some furriers also accept shipped coats and cover the cost of shipping.
