It is extremely important to treat all information available online as a general tendency or a rough estimate rather that real reflection of actual situations. One of my friend, Tom, was not aware of the fact that daily gold price per gram information available on so many websites for free would not help him estimate the exact price of his scrap gold. He was so happy when he found out one day that prices of gold had just gone up a bit. He had been waiting for the moment for months and he really needed some extra cash urgently. He consulted a few dealers almost immediately but what they offered him seriously disappointed him. When he calculated it, it turned out that they offered him only about 30% of the actual value of his scrap gold. I explained to him that no dealer and no pawn shop owner would ever offer him more. I added that they probably had to pay for the process of melting the gold down and other services so they were unable to offer more for the gold. But Tom was stubborn, as usual, and decided to keep searching. He finally found a buyer from Manchaster who offered to pay him 70% of the value. Tom managed to sell his gold just in time as a week or two after that gold price per gram went down drastically.
