No doubt that the precious metal business is great. You will earn good by purchasing at low and sell at high. But the difficulty came at who will buy such kind of precious metals. I think you should contact with jewellery dealers and other person who are able to buy these metals.
Why a jeweler? Jewelry only makes up 20% of the use of silver. Silver is the most important metal on earth. without silver there are no electrical devices, no electronics, no solar panels, no formaldehyde, no computers or cell phones, no missiles, no war heads, no cars or trucks, no airplanes or just about anything modern is possible without silver. Nothing that uses electricty is possible etc etc etc.....only about 10,000 different things that can only be made with silver. Every ounce of silver mined in the USA is used to make coins, every ounce. None of it is used to make jewelry.
If you want to sell your silver just go to a broker/coin dealer/PM Dealer and never take less than the spot price.
Even little towns of 10,000 people have a coin shop.
It is simplistic to find a buyer for precious metals, not even remotely difficult.
Only stupid people will sell their PM to companies like GoldTimes or send their jewelry into be appraised at 1/4 spot price. Those people are the suckers.
