As any avid numismatic knows, proof coins are a valuable addition to any coin collection. Minted purely for collection purposes, proof coins are struck under intense pressure and using specialised dyes. The aim, when creating these types of coins, is to strike a coin that is flawless: Free of blemishes, chips, scratches or other imperfections. Several techniques are used to achieve this outcome, as well as to produce the frosted devices, matte and mirror-like fields found on the coins.
It’s important to remember that the term “proof” doesn’t refer to a coin’s grade, but rather, to the high-quality manner in which it has been minted. In some cases, several hundred proof coins may be minted, while in other cases, only a handful of these collectors’ items are struck. Naturally, the rarer a proof coin, the greater its value is likely to be. This is also true of other types of coins, such as Krugerrands, gold, sliver and platinum coins and limited edition coins.
