How is a Proof Coin Different From a Regular Minted Coin?

By GovMint :

Proof coins and regular minted coins are crafted for different purposes, and this is reflected in their appearance and production process. A proof coin is struck using specially prepared dies and planchets (coin blanks), resulting in a highly detailed, mirror-like finish. The process often involves striking the coin multiple times at a lower speed and with higher pressure, ensuring that the design is sharply defined and the background has a distinctive smoothness. This meticulous approach contrasts with regular minted coins which are produced at a higher speed with a less specialized minting process, since they are primarily intended for circulation. Proof coins are often produced in limited quantities and are generally presented in protective packaging to preserve their condition, further distinguishing them from their circulating counterparts.

Proof coins are a testament to the artistry and craftsmanship of the minting process, designed to showcase the highest standards of numismatic beauty.
