50 Years of Proof Sets
While the first “modern” proof sets were issued by the Philadelphia Mint in 1936, the San Francisco Mint began distributing proof sets in 1968 following a three-year moratorium on proof set production from 1965 through 1967. San Francisco proof sets began in 1968 with the Lincoln cent, Jefferson nickel, copper-nickel clad Roosevelt dime and Washington quarter, and 40% silver Kennedy half dollar. The 1968 proof set was also the first United States proof set packaged in a hard plastic display case.
With the production of the first proof copper-nickel clad Eisenhower dollar in 1973 was the expansion of the regular proof set from five to six coins, which continued through 1981 with the last of the original Susan B. Anthony dollars. The 5-coin San Francisco proof sets returned in 1982 and continued through 1998, until the first 50 State Quarters were released in 1999 and proof sets subsequently grew to include these and other new issues during the first years of the 21st century.
The first 90% silver proof sets made at the San Francisco Mint were released in 1992. Since then, the number of proof set offerings has grown, with the United States Mint now distributing a half dozen or more different proof set products each year.
Proof Set Pricing Trends
The proof set prices has softened in recent years as an explosion of new US Mint offerings, lingering economic challenges, and changing hobby demographics have all affected the proof set market. For the most part, proof sets can now be bought at or below the prices that were paid 20 years ago, and many of the proof sets from the 1970s, ’80s, and ’90s can be bought for around or less than $5 apiece.
As the years go on, more and more proof sets are being broken up, with individual coins being parted out as singles for series collections and high-grade pieces are sent off to third-party coin grading firms for encapsulation. This means that the remaining number of proof sets in crisp, clean, original government packaging with certificates of authenticity (when applicable) is dwindling. Therefore, collectors and dealers who wish to buy proof sets might find now a good opportunity to buy and hold proof sets, especially if the market increases down the line as the market improves and should older proof sets in original packaging become scarcer.
