Proof gold

A proof coin is a coin struck using a special, high-quality minting process. These coins were historically produced for checking the production dies and for archival purposes, however nowadays these higher quality coins are often produced in greater numbers especially for coin collectors / numismatists.

Proof production usually involves polishing of the production dies and often uses chemicals to make certain parts of the design take a matt appearance, with the polished fields displaying a mirror finish. They can often be distinguished from bullion coins by their sharper rims and more defined design. An easy way to understand the different look between proof and bullion is to imagine the enhanced sharpness an HD television offers over standard definition.

Proof coins are sometimes sold in encapsulated tamper-proof plastic casing straight from the mint. The casing maintains their pristine condition, and integrity. Others may simply be presented in a wooden presentation box.

These coins are often produced in limited issue, often adding to their collectable appeal. Commonly proof coins will come in a set of several proof coins, perhaps including all fractional denominations of a certain coin. These sets are usually beautifully packaged and can make great presents.

The cost of proof coins is generally 10-25% higher than their bullion version, even though they have the same gold content and are of the same purity. When you come to sell a proof coin it is unlikely you will receive the full premium back, and for this reason these coins are not the best form of gold to purchase for investment purposes.
