The 1970-S Proof Kennedy Half Dollar is an important coin in American coin collecting history, famous for some coins selling for over $30,000 at auction. In this article we will discuss the reasons behind this coin’s high value, including its unique properties, limited production, and the important role played by the Double Die Obverse (DDO) mistake.
1970-S Proof Kennedy Half Dollar: A Primer
The Kennedy Half Dollar coin was introduced in 1964 to commemorate the U.S. President John F. Kennedy. The coin became a national symbol very quickly. The 1970-S Proof is also important because it is part of the last series with an admixture of silver (40% silver). An admixture increases the intrinsic value of the coin and, therefore, it is attractive to collectors who are fond of silver coins.
The most obvious reason why the value of the 1970-S Proof Kennedy Half Dollar has gone up is due to its low production. Only around 2.6 million Proof coins were produced, fewer than other years in the series. Such a scarcity makes the coin even more appealing to collectors looking to complete their collection of Kennedy Half Dollars.
Double Die Obverse Error
The most rare and valuable variant of the 1970-S Proof Kennedy Half Dollar is the Double Die Obverse (DDO) Mistake. The mistake occurs when the coin’s design is engraved twice, thus creating a double impression of words or numbers on the obverse (front side). Such coins are very few in number and sometimes can fetch over $30,000 at auction, especially when they are in immaculate condition.
Condition and Grading
In addition, the condition of the coin also leads to a notable impact on its market value. For instance, coins that grade PR68 or more are often regarded as having outstanding condition and are, thus, in more demand among collectors. The grade provided by professional grading companies, such as PCGS and NGC, will determine the coin’s value, since the grading will be conducted based on the condition of the coin.
This coin has some historical significance much beyond its inherent physical characteristics. It was minted in memory of President John F. Kennedy, who was assassinated in 1963, in honor of his contributions, and legacy it also marks the closing of the end of the age when half dollar coins were composed of silver metal, and later years this coin was constructed of base metals.
