The coins of the Classic Group (spanning from 1986 to 1991) have seen exceptional investment performance, with yearly price increases ranging from nearly 11% to 22% since 2010, far above average returns in the stock market or even the gold bullion market.
When the modern U.S. Mint began making gold coins in 1986, the first major release was the Gold American Eagle. Each year, the mint creates a standard "Business Strike" version of the coin, made for general bullion circulation, and a much smaller number of special issue "Proof" coins, specifically for investors and collectors.
Only a very small percentage of the proofs receives a "Proof 70" certification, a perfect score which establishes the rarity. The value of bullion coins floats up and down with the market price of gold, but rare coins, such as Gold Eagle Proof 70s, don’t trade on an index and are therefore much less volatile. Instead, their value is determined by supply and investor demand. These coins are also known as Investment Grade Coins.
In 1986, the first year of issue, the Mint only made a 1oz coin, with a $50 face value. In 1987, a 1/2oz coin with a face value of $25 was added to the series. Each subsequent year, the Mint has produced 4 sizes: 1oz, 1/2oz, 1/4oz ($10 face) and 1/10 oz ($5 face). All of the coins in the Classic Group feature Roman Numeral dates, which makes them unique among U.S. coinage.
