Vintage early 1980s authentic silver fox fur coat

This was my moms silver fox coat. She bought it in the early 1980’s from Godchaux’s department store for $700 in Baton Rouge, La after a big fight with my dad! 😂. She babied that coat for years! The lining is completely in tact, no rips or holes. There are light stains on the left inside, probably a little wine. See pics for detail. The coat has a leather tie closure and can be belted on the outside or on the inside. The coat (fur and lining) is in excellent condition and has been kept inside a closet in a smoke free pet free home. Grey leather gloves she always wore with it included. Tags say L but fits more like a M.
