I have used APMEX with good results. When prices were more stable in the spring the premium was significantly lower. With volatility such as it's been the premium is higher for Eagles and ML's If you are willing to pay by personal check and wait about three weeks the shipping is I think $20 regardless of the size. I paid $20 S&H for those green mint boxes with 500oz. Not bad, I thought. http://apmex.com/ Locally in MD I use Gaithersburg Coin Exchange with good results. g
I liked APMEX but recently they have gotten stingy so went back to NWTM even though they take longer to send your order. Try buying pre-1965 U.S. silver coins in half dollars @ APMEX. The ownwer tried to bilk me big time. NWTM was much better and just recently bought a $1,000 face bag although I probably should have waited as believe gold and silver might come down some more over the next month or so. Silver rounds and 100 ounce bars are the next best bet.
