You should be expected to pay at least 100 dollars for genuine coins. Maybe you are extremely lucky but chances are someone would have bid a much higher price than that. Clearly not.
Unless you REALLY know what you are buying, don't even attempt to collect Chinese coins. Start off with a catalog and low grade genuine coins unless you want to learn it the hard way.
