Most Valuable Half Dollar Coins in Circulation
Half dollars have a long history of minting quirks, silver content, and rare errors that make certain pieces far more valuable than their face value. Below is a refreshed look at the most desirable half dollar coins still surfacing in circulation today.
1964 (P) Kennedy Half Dollar
Introduced shortly after President John F. Kennedy’s assassination, the first-year half dollar struck in Philadelphia saw over 273 million pieces released. Since these coins are composed of 90 percent silver, even worn examples carry strong melt value. Most average circulated pieces trade in the $12 range, while lightly circulated AU58 coins usually sell near $14. Uncirculated grades bring much higher premiums but remain plentiful due to high mintage totals.
1964-D Kennedy Half Dollar
Denver’s 1964-D issue is marked with a D near the eagle’s talons. While low-grade examples may reach around $22, coins from Fair to AU55 are typically valued close to $13. Truly pristine examples are extremely desirable, with an MS68 specimen once selling for an impressive $22,325 at auction.
1964-D Double Die Obverse
Among the standout errors from Denver’s production is the double die obverse variety. This doubling can be spotted on the date and on the inscription IN GOD WE TRUST. Mid-grade examples often fetch $20, with higher-grade coins rising to around $32, making them attractive finds for error collectors.
1964 D/D Kennedy Half Dollar FS-501
The FS-501 variety exhibits an additional D mintmark positioned slightly above the original. These re-punched mintmarks create a noticeable visual anomaly. Extremely fine coins are valued near $19, with AU coins reaching around $27 and higher-end pieces around $38.
1964 D/D Kennedy Half Dollar FS-503
This variation shows the second mintmark shifted to the left of the primary D. Although not as rare as the FS-504, it still brings solid collector interest. Extremely fine examples usually begin around $18 and increase as condition improves.
1964 D/D Kennedy Half Dollar FS-504
Considered the scarcer of the major RPM varieties from 1964, the FS-504 version often commands stronger prices. Coins in around grade 50 may bring $30, while upper AU pieces can reach values of $45 or more.
1972-D Kennedy Half Dollar No FG
One of the most desirable modern half dollar errors is the 1972-D missing the FG initials of engraver Frank Gasparro. The absence is believed to result from either a damaged die or over-polishing. Even moderately circulated examples are highly valuable, with values around $275 and increasing substantially with higher grades.
1974-D Kennedy Half Dollar Double Die Obverse
Recognized as the only major doubled die in the Kennedy half dollar series, this 1974-D error shows strong doubling on the obverse, especially in the phrase IN GOD WE TRUST. While circulated examples are usually under $40, specimens in exceptional condition may bring more.
1976-S Silver Kennedy Half Dollar
Minted for America’s bicentennial celebration, these San Francisco coins contain 21 percent silver and 79 percent copper. Despite their collectible status, most circulated examples fall in the $6–$7 range due to relatively high production numbers.
Final Verdict
Rare half dollars continue to surface in circulation, especially in older coin rolls, inherited collections, and forgotten savings jars. From silver-rich 1964 issues to high-value errors such as the 1972-D No FG, the half dollar denomination offers many opportunities for collectors to discover hidden value. Keeping an eye out for mintmarks, doubling, and unusual features can make all the difference in spotting a treasure.
