The value of a 1967 Kennedy 50-cent piece is determined primarily by two factors: its intrinsic metallic content and its numismatic condition, or grade. It is important to first clarify the coin's composition. Unlike the 1964 issue which was 90% silver, the 1967 half dollar is composed of 40% silver. This structure consists of outer layers of 80% silver and 20% copper bonded to a core of 20.9% silver and 79.1% copper, for a total silver weight of approximately 0.1479 troy ounces.
For the vast majority of 1967 half dollars that entered circulation and show signs of wear, their value is directly tied to this silver content. This is commonly referred to as the coin's "melt value," which fluctuates daily with the market spot price of silver. Consequently, a circulated specimen is typically worth the current market value of its constituent silver, which is usually a few dollars.
A significantly higher value is possible for coins that were never circulated and remain in pristine, or "Mint State" (MS), condition. Numismatic value for these uncirculated coins is assessed on a grading scale, and the higher the grade, the greater the rarity and value. A low-end uncirculated coin, such as one graded MS-60 to MS-63, will carry a small premium over its melt value. However, this premium increases substantially for coins in higher grades. For instance, a 1967 half dollar graded MS-65 is considerably more valuable, and specimens achieving exceptionally high grades like MS-66 or MS-67 are rare and can be worth hundreds or even thousands of dollars at auction.
It is also noteworthy that in 1967, the U.S. Mint did not produce traditional proof sets for collectors. Instead, it issued Special Mint Sets (SMS). These coins have a distinct satin-like finish that differs from both standard business strike and proof coins. A 1967 half dollar from an SMS set, particularly in a high state of preservation, will often command a higher price than a standard business strike coin of a similar grade. Finally, all 1967 half dollars were struck at the Philadelphia Mint and, as was standard for that facility at the time, do not bear a mint mark.
