These are all my recent purchase of silver coins a sort of hobby as well as a long term investment. I started collecting silver coins when my wife gave me some pieces of 1975 coins and we decided to sell it thru online. We actually dont knew the price range of our coins and just calculated it in its metal content value. but a local collector who saw our posting online contacted us that we can sell the coins at a price range of $20 to $30 and the coins were sold approximately $25 each. From that moment, my interest in precious metals specially silver coins started to grow. I spend most of my free time to study more anything about world's silver coins.
