I've decided that I'm ready to start building a position in Silver. After initially thinking I might sort halves, as I do pennies, I've decided that I will be a buyer in the world of Silver, and not a sorter.
I've found myself on apmex.com, looking at what they have, but I really don't know where I ought to be doing my shopping. I'm going to be getting in VERY slowly, as that's all my finances will allow at the moment.

What do you recommend? Eagles? Bars? Rounds? Bellybutton rings?
Any thoughts?
