What is a proof coin?

Imagine before you are two Silver American Eagle coins from the U.S. Mint, widely regarded as the most popular bullion coin in the world. They are of the same year, same weight and same purity of 1 troy ounce .999 Silver. Yet one is a proof coin and one is a standard coin. You may be surprised to learn the proof coin is more valuable than the standard coin.


Rarity and beauty of proof coins

What is a proof coin? Proof coins are defined by their method of manufacture, rather than their grade. Proof coins are made in relatively low quantities and feature a more reflective or cameo appearance. Some collectors describe them as appearing frosted and more beautiful than the regular bullion issues. These coins are struck using specially polished dies, which may be sandblasted or treated with chemicals. The coins may also be struck more than once or with significant pressure. These coins are made specifically for collectors and are not intended for circulation. Because of the extra care taken in striking the coin, details in the design may stand out more and the field area may appear smoother than on a standard circulated coin.


Purchasing proof coins through APMEX

Proof coins are often available in specially certified packaging or in coin proof sets. For example, APMEX carries a proof coin set of uncirculated coins from 1958, including a Lincoln cent, a Jefferson nickel, a Roosevelt dime, a Washington quarter and a Franklin half dollar. U.S. Mint Gold coins are also available in proof sets from APMEX, including a proof coin set of Gold American Eagles in denominations of $5, $10, $25 and $50. Dozens of additional examples of proof coins are available in the APMEX inventory.

For collectors who value beauty and rarity, proof coins are well worth the premium.
