What Is a Proof Set?
A proof set is typically a set of coins, one of each denomination for a particular year. You would have one penny, one nickle, one dime, one quarter and one half-dollar of a specific year in one set. There are also special proof sets, such as the Presidential Dollar series or the Silver State Quarter series.
How Proof Sets Are Made
Proof sets are unique in appearance because they have a "mirror" look to them. This appearance is produced by striking the coin more than once with special polished dies. The image on the coin also has a raised frosted look to it, while the background is similar to a mirror, enhancing the details and beauty of the coin.
How Proof Sets Are Sold
Proof sets are sealed in their own packaging. When they were first produced in the late 1930s, the coins were sealed in individual cellophane wrappers. Today they are individually sealed in an acid-free hard plastic holder and placed into a box. Proof sets can be purchased from dealers, online or through the U.S. Mint.
Value of Proof Sets
Proof sets go up or down in value depending on a number of variables and the good old "supply and demand" platform. Two excellent books any coin collector must have is the most current edition of "A Guide Book of United States Coins Red Book" (retail value) and "A Guide Book of United States Coins Blue Book" (wholesale or dealer values).
Caring for Proof Sets
Modern day proof sets are sealed in hard plastic and placed in their own box. However, there are storage boxes that hold multiple proof sets conveniently and safely. There are even specially made storage boxes, such as the Intercept Shield box, that prevents corrosive gases from coming into contact with your coins and discoloring them.
