CoinWeek Giveaway # 666 Sponsored by…
Three Special Mint Set (SMS) Kennedy Half Dollars 1965–1967 Plus
Rick Tomaska’s Guide Book of Franklin & Kennedy Half Dollars
Three Kennedy Half Dollars From the Years Proof Sets Disappeared
A 1965 Kennedy half dollar, a 1966, and a 1967 may seem like a straightforward three-date run. But these are not ordinary circulation strikes. Each comes from the United States Mint’s short-lived Special Mint Set program, a stopgap that turned an extraordinary coin shortage into one of modern numismatics’ most distinctive collecting opportunities.
For CoinWeek Giveaway #666, one winner receives all three SMS Kennedy half dollars, each graded MS-67 Star, plus the fourth edition of Rick Tomaska’s A Guide Book of Franklin & Kennedy Half Dollars. Together, the four prizes tell a story that goes far beyond their 50-cent denominations.
When the Mint Stopped Making Proof Sets
President John F. Kennedy’s half dollar debuted in 1964, amid intense public demand for a tribute to the slain president. At the same time, rising silver prices and the hoarding of older silver coins strained the nation’s supply of circulating change.
The Coinage Act of 1965 removed silver from dimes and quarters and reduced the Kennedy half dollar’s silver content from 90% to 40%.
The Mint suspended annual Proof and Uncirculated sets and removed mintmarks from coins dated 1965 through 1967. Instead, collectors could buy five-coin Special Mint Sets for $4.
Alongside the Kennedy half dollar came a Lincoln cent, Jefferson nickel, Roosevelt dime, and Washington quarter. All were produced at the San Francisco Assay Office despite carrying no S mintmark.
Three Years, Three Personalities
The 1965 SMS Kennedy half dollar usually shows a soft satin finish. The following year’s coins often appear brighter, while 1967 examples can display strongly reflective fields and frosted portraits.

Specialists prize those particularly dramatic Cameo and Deep Cameo pieces. However, the three coins in this giveaway carry the MS-67 STAR grade.
Each half dollar contains 40% silver. More importantly, the trio forms a complete date set of the SMS Kennedy half dollars, a brief chapter between the 1964 Proof coinage and the return of Proof sets in 1968.
Collectors can examine the coins side by side and follow how the Mint refined its experimental finish. The differences become more apparent under angled light, especially around Kennedy’s portrait.
The Fourth Prize: Knowledge for the Collector
The winner also receives Rick Tomaska’s fourth-edition reference, published by Whitman in 2023. Its treatment of Franklin and Kennedy half dollars covers designs, grading, die varieties, auction markets, and the critical differences between ordinary surfaces and striking Cameo contrast.
That makes this giveaway more than three certified coins and a book. It gives one collector the entire three-year SMS Kennedy half-dollar run and a serious reference for appreciating what makes those coins special.
