Gold and Silver Eagles are consistently the most popular bullion release by far each year. The Eagle Coin Series are unquestionably the most iconic bullion coin series of all-time, with over 530 million silver eagles and over 19.1 million gold eagles minted since the series’ inception in 1986. Recently, mintage numbers for the Gold Eagle have been decreasing, going from 1.5 million in 2009, to 817,500 in 2016, all the way down to 191,000 pieces in 2018. It is unknown if this trend is going to continue, but it does seem that the US Mint plans to be more limited with their gold eagle mintages as the years go on.
The American Gold Eagle is minted using 22-karat gold (.9167 in purity) and contains one troy ounce of pure gold in total. This means that the coin itself will be larger than coins like the Gold Maple Leaf which has a purity of .9999, so the eagle will still contain one ounce of pure gold.
