VINTAGE NAVY GRAY FAUX FUR LINED CROWNWEAR COAT 48 REG NEEDS TLC

Up for sale is a vintage coat used by my dad in the 1980s and 1990s. It shows some general wear, a few spots here and there, etc. The lining is like a fur, but the cloth tag says 100% polyester so I'm assuming it's faux fur. The worst issue is it's missing an original front button (see close-up). Could be a really nice statement piece with a little TLC!
