The value of a 1968 Kennedy Half Dollar is determined by two main factors: its silver content and its numismatic or collectible value, which is based on condition and mint mark.
All 1968 half dollars are composed of 40% silver. This gives them an intrinsic "melt value" that is always higher than their 50-cent face value. The melt value fluctuates daily with the spot price of silver but typically places the coin's base worth at several dollars. For a common, circulated 1968 half dollar, this silver value is its primary source of worth.
There were two versions of the coin minted in 1968. The most common version was produced for circulation at the Denver mint and has a "D" mint mark. In circulated condition, it is worth its silver melt value. If the coin is in uncirculated, mint-state condition, its value increases for collectors, often ranging from $5 to $10. Coins in exceptionally pristine condition, as certified by a professional grading service, can be worth more.
The second version is a proof coin struck at the San Francisco mint, which bears an "S" mint mark. These coins were specifically made for collector proof sets and were not intended for circulation. They have a brilliant, mirror-like finish and are generally more valuable than their Denver-minted counterparts. A typical 1968-S proof half dollar is often valued in the range of $5 to $15, depending on its specific grade and quality.
