Help identifying uniforms

I just purchased these at an online auction. It seemed no one was interested and I bought them all for a great price. In total there are 3 pairs of pants and 1 overcoat. I'm trying to determine if they are in fact genuine and what these may be worth. I purchased them to flip them and I'm hoping they are genuine. The pants all have repairs and the coat has some small burns and holes. I see 1 pair of pants are marked c&d inside. Any help is appreciated.
