Brass Coin Blank 44mm Brushed 4mm thick

Solid brass coin blank, 44mm (1.75") in diameter and a substantial 4mm thick — the most popular challenge coin size. The brushed finish engraves crisp, deep, and high-contrast on fiber and galvo lasers, and polishes to a mirror shine if you prefer a bright finish.

Each blank is solid brass, not plated, so you can engrave deep relief designs, anneal, or patina without exposing a different base metal.

Specs: 44mm diameter · 4mm thick · solid brass · brushed finish, both faces
