You may disagree with some of these, but I think it's a pretty good place to start for new investors:
http://the-moneychanger.com/commandments.phtmlI. Always take delivery
II. Never buy premium if you can avoid it.,III. Buy bullion for business, numismatics for fun.IV. Buy silver first, then gold.
V. Buy small gold first, then large.
VI. Never buy exotic coins or modern rarities or anything you don't understand.VII. Know your dealer.
VIII. What governments can't find, they can't steal.
IX. Never swap bullion coins for U.S. $20 gold pieces. (*)
X. Never break the law.
(*) - This one I especially disagree with, if you can get pre-1933 gold for low premium/close to melt-by all means get it! Just don't "trade up" for expensive slabbed coins.
Anyway, sounds like you want to get started with a high premium, semi-numismatic, modern rarity that you don't understand. On top of that, I don't think they minted proof Gold America Eagles in 2009? I'd pass.
