One of the best strategies is to get on a regular buying schedule. Set so much aside every month, and start collecting graded silver eagles, canadian mapleleafs, or libertads. Maybe limit yourself to one or two ounces a month. Pick those that are in high demand, as reselling is easier, and usually more lucrative. I like the five ounce mint products, like libertads or the america the beautiful series 5 ounce rounds. Again, good fortune to you. S~P
