What is Sandblasting

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.

Challenge Coin Customer Reviews

Extremely Impressive / best Customer Service!!!

trustpilot-stars

I have rarely worked with a company that was so willing and able to go above and beyond to provide a product - they worked with me through changes and last minute requests - and did it all with a willing, can do, happy attitude. Once of the best companies I have ever done business with. Additionally, EXCELLENT product. The coin was exactly as ordered, quality product, impressive!!
