Understand the difference between Silver bullion with proof or reverse proof finish.

When buying coins, a proof coin is the finest quality coin made especially for collectors using a high-quality minting process which often includes striking the coin at least twice, giving the design even more definition. Proof coins have beautiful mirrorlike fields (the flat, empty spaces) and frosted devices (the images that are raised up). Mexican Silver coins, or any coin, that is a reverse proof is struck with the same precision and method as a proof, except that the field is frosted and the device is mirror-like. The name reverse proof can sometimes cause confusion. When you buy reverse proof coins, the entire coin is in reverse proof finish, not just the reverse side of the coin.
