Lynne, you're the best!
I vote for the 60s too and you can see the ad has a price of $80 which is like $600 today but prices then are incomparable to today. Clothing has actually become cheaper to produce. The label isn't a big name but the coat is certainly special. Yours looks like a swing clutch coat to me so perhaps you could do a search for similar coats by other makers and add extra to the price for the fox cuffs. Fur can be a catch-22; most buyers dislike fur these days but since it's only on those cuffs which simply make the coat, don't think it'll be an issue for you.
