Crafting Your Own Custom Coin: A Step-by-Step Guide

Coins hold a timeless allure, from their diverse shapes and materials to the intricate designs engraved on them. Imagine having your very own personalized coin - a tangible token of uniqueness. In this blog post, we delve into the art of creating a custom coin using a CNC mill. Let's explore the process, from design to the final finishing touches, and elevate your craftsmanship skills!

Unleashing Your Creativity: Designing Your Coin

Coins have adorned the palms of gods, kings, and even fictional characters, each bearing a unique identity. To begin crafting your coin, you have two distinct methods at your disposal:

Method 1: Utilizing a 3D Model

Obtain a 3D model of your desired head using software like Autodesk's 123D Catch.
Bisect the model and adjust its dimensions to fit on the coin.
Develop the coin's surrounding features to guide the CNC mill during the milling process.

Method 2: Converting a Photo into a Depth Map

Transform a photo into a depth map, reflecting varying depths through gradients of gray.
Displace coin geometry using the depth map in your 3D software.
Refine the design iteratively to achieve the desired look.

Milling Your Masterpiece: Bringing the Coin to Life

The milling phase is where the magic unfolds, transferring your design onto a piece of brass with precision and finesse:

Secure the workpiece adequately, especially when milling metal, to avoid undesired vibrations.
Employ an engraving cutter for detailed work, taking your time to mill with precision.
Conduct both roughing and finishing passes to achieve the desired outcome.

Adding Character: Enhancing Your Coin's Appearance

A bare metal coin might seem lackluster, but fear not - there are ways to infuse life into your creation:

Explore methods of creating patination, such as using a blowtorch to oxidize the surface.
Experiment with matte black spray paint and metal polishing compounds to create a layered patina.
Finish off with a touch of linseed oil for a darker hue and a polished finish.

Elevate the Presentation: Crafting a Custom Coin Box

Why stop at just the coin? Enhance the overall presentation by creating a bespoke coin box:

Mill a sophisticated box with precision, incorporating hinges and neodymium magnets for a seamless closure.
Design deeply recessed coin slots for easy removal and a touch of elegance.
Add a touch of oil or varnish to the finished box for a professional look.
