These Junk silver coins were hoarded upon their release in March 1964 by collectors and those interested in a memento of the late president. Although the U.S. Mint greatly increased production, the denomination was seldom seen in circulation. Continued rises in the price of silver increased the hoarding—many early Kennedy half dollars have been melted for their silver. 1964 Silver Kennedy Half Dollar is 90% silver, while the 1965-1970 is 40% silver. The silver content technically makes these coins Junk Silver. The 1968-D, 1969-S, and 1970-S, were only issued in Proof sets.
Listed below are the mintage numbers for each year. The year column lists the year and mint mark on the coin where, D is for Denver, S is for San Francisco, and P is for Philadelphia. Also, a coin without a mint mark means the coin was minted in Philadelphia.
The Mintage column is the number of coins struck and released by the U.S. Mint.
