Full-length mink coats can be the most valuable of all fur coats and can cost $10,000 or more for a high-quality coat. Even lower-quality full-length mink coats can be priced in the thousands. They can come in a variety of styles and colors and despite their high value, can depreciate in price over time due to wear and tear, style changes and even market demand. You can get the value of a full length mink coat by checking its coverage, amount of pelts and color.
Take notice of the pelts. Mink pelts can come from either male or female minks. Male pelts are normally larger and a coat will require fewer pelts. Female mink pelts are more valuable, however, and a full length mink coat will require a larger quantity of pelts if it comes from a female.
View the color of the mink coat. Full-length mink coats can come in a variety of colors and styles but the most valuable ones have richer tones, no spotting and a clarity of consistent color throughout the coat.
Inspect the coat for any damage such as markings, rips, stains or tears. Locate the manufacturer's name on the tag and try to compare the style and length with similar styles you can find from the same manufacturer online at auction sites or high-end, custom retailers.
Feel the coverage of the mink coat. A think, full and plush mink coat is a lot more valuable than one that has sparse coverage. Check the density as well, this is the amount of hairs that cover the coat. The less dense, the less valuable the coat is.
Ask a local fur dealer for an appraisal. At the time of this publishing, an appraisal can cost between $25 to $50. You can use an appraisal to insure the coat or to sell it.
