I have never seen any reference material on Bergbau uniforms. As they did nt incorporate a swastika into their insignia, it would be difficult to date the era of this tunic. Possibly our resident guru Wilhelm Saris can shed some light on the subject. It is not something that I would think would command much of a price.
LIFE'S LOSERS NEVER LEARN FROM THE ERROR OF THEIR WAYS.
I had a hell of a time trying to find Bergbau reference myself. Also, you were quite correct in your prediction, it sold for $80.
