ModernCoinMart carries 1/2 oz. American Gold Eagles in both collector and bullion versions. Coins graded by the Numismatic Guaranty Corporation (NGC) or by the Professional Coin Grading Service (PCGS) are an ideal option for those looking for a precise grade and professional encapsulation. Uncertified coins are carried exactly like they come from the U.S. Mint and offer a low premium over spot.
