Like the American Gold Eagle, the American Platinum Eagle is made in several sizes. In addition to the 1 oz. Platinum Eagle, the U.S. Mint produces 1/2 oz. Platinum Eagles, 1/4 oz. Platinum Eagles, and 1/10 oz. Platinum Eagles.
The variety of fractional Platinum Eagle sizes makes this coin affordable on practically any budget. If you're looking to spend as little as possible, start with a 1/10 oz. Platinum Eagle. You may pay a higher premium as compared to the 1 oz. Platinum Eagle, but the overall cost will be much lower.
There is also a distinct advantage to purchasing multiple fractional Platinum Eagles as opposed to a single 1 oz. Platinum Eagle. When it's time to sell or trade, if you bought a 1 oz. coin then you only have 1 coin to sell. In comparison, if you purchased four 1/4 oz. Platinum Eagles then you would have four coins to sell or trade. You could part with all of them, just one, or a few. Purchasing fractional bullion coins definitely offers a higher level of flexibility as opposed to a single larger bullion coin.
Like other coins from the U.S. Mint, the MCM staff makes every effort to create the best selection of Platinum Eagles possible. When you're ready to add another Platinum Eagle to your collection, always be sure to check MCM!
