Proof coins are specially-made collectible coins that are struck at least twice with heavily polished dies to achieve a mirror-like finish on the background and a matte finish on the foreground. They are created using the same minting process as regular coins, but with additional steps to ensure high-quality strikes. The term "proof" refers to the coins finish, not its condition. Proofs are often sold directly by the government mint in proof coin sets and have lower mintage totals than their non-proof counterparts. They are intended to be saved in collections and are not distributed to banks for circulation.
Some key features of proof coins include:
-
Appearance: Proof coins have a much shinier, clean-looking finish than regular coins, and the intricate details of the design pop. They are easily distinguishable from other coins in that the background is very reflective, and the foreground is matte.
-
Value: Generally speaking, proof coins have a higher relative mark-up than uncirculated coins. As a collector’s item, proofs can be sold for more than the value of the raw precious metals they contain.
-
Rarity: Proof coins are also rare, since only a small number are minted. This rarity increases their value.
Proof coins are different from bullion coins, which are sold for investment purposes and are rarely considered collectible. They are also different from uncirculated coins, which are created in larger quantities and may have blemishes.
