Technically a precious metal bullion producer, the U.S. Mint is also an online dealer via their online catalog at http://catalog.usmint.gov  After all this is were it all begins for the U.S. bullion coins. The best deals for any new issue will be found here, no doubt about it. In todays bullion coin market very good gains can be realized by simply buying a new issue and holding it for six months to a year. Many issues there is no wait at all. For instance the recent 2007-W Silver American Eagle $1 (1oz silver) Uncirculated coin which is now sold out could be purchased via the mint for $21.95 and immediately listed on ebay where most "ungraded" listings are fetching minimum of $28 to $30. That's roughly at least 20% instant gain. You may ask, "Why don't people just buy from the mint?" Good question, I have no answer. That particular issue, now being sold out, should increase in value over the years. Hint: The 2007-W Silver American Eagle Proofs, still available as of today at the mint for $31.95, are seeing similar immediate increases in value on aution sites.
