As long as it is in perfect and clean condition, it would have some value, but nothing very high. The style is pretty common to the 50s and 60s eras, and without a spectacular fur collar or great new look cut, I've had trouble moving this type of coat.
If that's the satin I think it is, that heavy vintage satin, ooooooo.....I have a thing for that satin. It's so lux!
If you want to try to sell it, show it on someone hip and young that fits well in it.
