A friend is into buy and sell business of antique items. He has the eyes and the feel on the authenticity of the antique. I have some antique items here but it is more of technology like a small floppy disk and the oldest mouse. But for other items like the writing table of my grandmother, I know it is authentic so probably I have to consult my expert friend if I am going to sell that antique writing table. In talking to a buyer you need to have a basis for your price otherwise you can lose in the haggling battle.
