You see, the United States Mint didn’t make mint sets in 1965 — at least not the type of mint set we’re used to seeing.
In 1965, 1966, and 1967, the United States Mint made special mint sets. Special mint sets (or SMS) contain one coin of each denomination in proof-like condition.
Because mintmarks were not included on U.S. coins during 1965, ’66, and ’67, the 5 coins in these special mint sets are the only ones you’ll need to complete a collection of U.S. coins from those years.
Incidentally, 1965 was the first year of copper-nickel clad coinage in the United States.
A 1965 special mint set is worth $6 to $8.
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) and have won multiple awards from the NLG for my work as a coin journalist. I'm also the editor at CDN Publishing (a trusted source for the price of U.S. rare coins), editor at the Florida United Numismatists Club (FUN Topics magazine), and author of Images of America: The United States Mint in Philadelphia (a book that explores the colorful history of the Philadelphia Mint). I've contributed hundreds of articles for various coin publications including COINage, The Numismatist, Numismatic News, Coin Dealer Newsletter, Coin Values, and CoinWeek. I've also authored nearly 1,000 articles here at The Fun Times Guide to Coins — and I welcome your coin questions in the comments below!
