his set includes 12 brass blank challenge coins (blank coins for engraving), made of premium solid brass with a protective coating to prevent oxidation.

• 【Premium Quality Material】Our brass coin blanks and brass coins are crafted from high-quality solid brass, featuring a smooth brushed or glossy surface. The non-electroplated brushed brass may have slight traces, while all blank coins are coated with a protective layer to prevent oxidation, ensuring durability and long-term use without fading or deforming.
• 【Perfect for Custom Engraving】Our blank coins for engraving and challenge coin blanks are designed with a blank, flat surface (1.57in diameter, 0.157in thickness) that provides ample space for precise laser engraving, stamping, and etching. Removing the protective coating before engraving ensures clearer, more refined personalized designs, making these blank coins ideal for custom patterns, names, logos, or commemorative details.

All brass coin blanks are organized in a plastic case for easy storage, access, and overall protection, suitable for both personal collection and professional use.
