Also known as abrasive blasting, sandblasting is a process by which an abrasive media (typically sand) is forcibly propelled against a surface. Often, this process is used to strip down and clean a surface much like pressure washing.
As it relates to your challenge coins, sandblasting is texturing applied to the recessed areas of the coin to increase contrast. This is especially important on coins making use of the High Polish plating options. The sandblasting texture is built into the coin mold used to create your coins.
