Brass Coin Blank 50mm CNC Machined 4mm Thick

Solid premium brass, 50mm diameter & 4mm thick, finished on both faces — not plated, so you can engrave deep relief, anneal, or patina without ever exposing a different base metal underneath.

This run is CNC machined rather than laser cut, which means true circularity and consistent diameter — they seat the same way every time in a coin chuck or multi-coin jig. There's a small chamfer on the edge too: invisible, but it takes the sharp edge off when you're handling a stack or handing a finished coin to a customer. The surface is a smooth circular brushed finish, replacing the linear brushed surface of earlier runs.

Loading a lot of these? The Multi-Coin Jig x5 holds five at a time — and consistent machined diameters are exactly what makes a multi-coin jig worth using.
