I really want to buy my first gold coin, I think it will be a 50 peso or a maple leaf ounce coin as they have the best premiums. (Unless someone cares to recommend something better). I am going to buy it through provident metals, but im scared. Is there any way to tell if the coin is real? Provident meyals buys from the general public and that seems dangerous to me. I have read these stories of gold plated tunston how can I tell?
