Collectors can have their gold Kennedy half-dollars or any coins appraised online for free on websites such as Appraisemycoins.com, where they can search for the coin or directly contact a representative. Michael S. Fey founded Appraisemycoins.com as a way for coin collectors to get information about their coins.
The value of a gold Kennedy half-dollar is hard to determine because the U.S. Mint still sells the 50th Anniversary Kennedy 2014 Half-Dollar Gold Proof Coin for $1,165 as of July 2015. The government makes the coin out of 0.75 ounces of 24-karat gold and packages it in a custom wood display box.
Factors such as the condition, rarity and market value of the coin affect its overall value. Collectors should note that cleaning a coin doesn't increase the value of the coin. Cleaned coins are worth less to coin dealers than dirty coins because the cleaning process can be abrasive, which is why collectors should never clean their coins.
While collectors have to special order the gold Kennedy half-dollar, traditional Kennedy half-dollars are very common. Kennedy half-dollars from years 1964 through 1970 are worth more because of their silver content. Starting in 1965, however, the government reduced the amount of sliver that it used in the minting process from 90 percent to just 40 percent. From 1971, it minted the coins from copper and nickel, removing silver altogether.
