what is the best way to buy silver bullion? For example somewhere where you can buy it for 12.5 per ounce, then sell it back for 12.5 per ounce.
If it was that easy we'd all be rich. There is always a spread between buy and sell prices. Otherwise, the people who buy and sell it would be out of business.
http://www.nwtmintbullion.com/silver.php If you want silver bullion, you probably want bars or rounds. I think this site a a good place to get them. The prices are good and you'll get nicely packaged new pieces and not something that's been dinged up over the years.
I agree. There will always be a spread between bid and ask prices. Look at a site like Monex or APMEX and you will see exactly what their buy/sell spreads are. As for buying silver, many people like to buy rolls of 1 ox American Silver Eagles or 100 oz. silver bars.
I think what your really looking for is a shovel, hammer, pick, etc and a piece of land where Silver may be found. This way you dig it up, melt it down, sell it for what ever you want. Advantages here is you may also find Gold, Platinum, Uranium, Oil. The disadvantage is naturally claim jumpers.
