Here is a quick guide to help beginers not to get scammed when buying Silver.
To provide a different perspective... collecting coins is good because they are well known and they may appreciate in value. On the other hand, bullion (bars and rounds) is not as appealing to collectors, but you are getting more actual metal for your money. If you pay 33 dollars for an ounce of silver when raw silver is 30/ounce, then you are paying 10% for the coining. I tend to buy as close to spot price as I can.
