As a coin collector, you will encounter numerous different types of coins, but none is more beautiful than a Proof Set.  

What Is a United States Mint Proof Set?

In the early 19th century, the U.S. Mint started making proof coins, which were essentially specimen examples of existing currency. To make them more appealing to collectors, the Mint added a unique finish to the coins.

In the beginning, proofs were not made for every coin produced for circulation, but in 1936, that changed. The U.S. Mint began making proof sets and selling them to coin collectors.

What Makes Them Attractive to Coin Collectors?

Proof sets are unique in that they were never circulated and, therefore, have no signs of wear. They also offer a snapshot of currency frozen in time, assembled in a set with other coins from the same year. You can enjoy them as a group instead of having to search for individual coins.

Which Proof Sets Are the Most Valuable?

As is true throughout the field of numismatics, some proof sets are valued higher than others due to the year or errors they contain. For example, the earliest regular proof sets—those created between 1936 and 1951—garner higher prices than later sets.

Random errors also go for a premium, such as the 1970-S Roosevelt dime, 1971-S Jefferson nickel, and 1990-S Lincoln cent, which are all missing the “S” mint mark on the obverse side.
