The 1964 proof set was the last year regularly circulating coinage was offered in proof condition until the silver proof sets of the 1990s.
Beginning in 1965, the major denominations went to a copper-nickel clad composition. Even the half dollar was reduced to a 40% silver composition in 1965.
The 1964 proof set is one of the most popular proof sets and among the most affordable of the silver proof sets.
A 1964 proof set can be bought for anywhere from about $14 to $20 from most coin dealers.
I’m a roller coaster junkie, a weather enthusiast, a frequent traveler, and a numismatist. My love for coins began when I was 11 years old. I primarily collect and study U.S. coins produced during the 20th century. I’m a member of the American Numismatic Association (ANA) and the Numismatic Literary Guild (NLG). I’ve also been studying meteorology and watching weather patterns for years. I enjoy sharing little-known facts and fun stuff about coins, weather, travel, health, food, and living green… on a budget.
