Turn Spare Change into Treasure: A Comprehensive Guide to Making Stunning Coin Rings

Coin rings are a fascinating blend of history, craftsmanship, and personal expression. Turning a simple coin into a wearable piece of art is a rewarding experience, and this comprehensive guide will walk you through the process step-by-step. Whether you’re a seasoned jeweler or a complete beginner, you’ll find everything you need to know to create your own unique coin rings.

## Why Make a Coin Ring?

Before we dive into the how-to, let’s consider why coin rings are so appealing:

* **Uniqueness:** Each coin has its own history and character, making every ring one-of-a-kind.
* **Affordability:** Using readily available coins keeps the cost of materials low, making this a budget-friendly craft.
* **Sustainability:** Upcycling old coins gives them a new lease on life, reducing waste and promoting resourcefulness.
* **Personalization:** Choose coins that have special meaning to you, commemorating a significant year, country, or event.
* **Satisfaction:** There’s a profound sense of accomplishment in transforming a simple object into something beautiful and functional.

## Choosing the Right Coin

The success of your coin ring depends heavily on the coin you select. Here’s what to consider:

* **Metal Composition:** This is arguably the most crucial factor. Many modern coins are made from base metals like copper, nickel, or zinc, which are difficult to work with and may tarnish easily. Look for coins made of:
* **Silver:** Silver coins are ideal due to their malleability and resistance to corrosion. Older silver coins (pre-1965 US dimes, quarters, and half dollars) are excellent choices. Pure silver (.999) is too soft on its own for daily wear. Sterling silver (.925) is often alloyed with other metals for added strength, making it suitable.
* **Copper-Nickel Clad:** While not as desirable as silver, some clad coins (like certain US quarters and dimes) can be used. However, be aware that the copper core may become visible over time, especially on the edges.
* **Other precious metals:** Gold coins are also excellent but expensive.
* **Size and Thickness:** The larger and thicker the coin, the more material you have to work with, resulting in a wider ring. Consider the desired width and overall size of your finished ring when making your selection. Larger coins (like silver dollars) are better suited for larger ring sizes.
* **Design and Detail:** Choose a coin with an attractive design that will translate well into a ring. Consider how the image will be positioned and how much of the design you want to retain. Portraits, emblems, and inscriptions can all add character to your ring.
* **Condition:** While a pristine, uncirculated coin might seem like the best choice, slightly worn coins are often preferable. Excessively worn coins may be too thin or lack detail, but coins with a little character can add to the ring’s charm. Avoid heavily damaged or corroded coins.
* **Legality:** Always ensure that it is legal to deface the chosen coin in your jurisdiction. Some countries have laws prohibiting the alteration of currency.

Popular Coin Choices:

* **US Silver Dimes, Quarters, and Half Dollars (pre-1965):** These are readily available and contain 90% silver.
* **Morgan and Peace Silver Dollars:** Larger coins offering more material for larger rings.
* **Walking Liberty Half Dollars:** Known for their beautiful and intricate design.
* **Foreign Silver Coins:** Many countries have silver coins that can be used, offering unique designs and historical significance.

## Tools and Materials You’ll Need

Before you begin, gather all the necessary tools and materials. This will ensure a smoother and more efficient crafting process.

* **Coin:** The star of the show! Choose your coin carefully based on the criteria discussed above.
* **Coin Ring Making Kit (Optional but Recommended):** These kits usually include most of the following tools. However, you can acquire tools individually, especially as you grow in the craft.
* **Safety Glasses:** Essential for protecting your eyes from metal shavings and debris. Wear them at all times during the process.
* **Gloves:** Protect your hands from sharp edges and potential skin irritation.
* **Center Punch:** Used to create a starting point for drilling. This prevents the drill bit from wandering.
* **Drill:** A drill press is ideal for accuracy, but a handheld power drill can also be used. Variable speed is a plus.
* **Drill Bits:** A set of various sizes, including a small pilot drill bit and a larger bit for creating the initial hole. Cobalt drill bits are excellent for working with harder metals.
* **Step Drill Bit (Unibit):** This cone-shaped bit creates a smooth, gradually widening hole. It’s essential for achieving the desired ring size.
* **Ring Mandrel:** A tapered metal rod used to shape and size the ring. A steel mandrel is more durable than an aluminum one.
* **Mallet (Rawhide or Nylon):** Used to gently hammer the ring onto the mandrel for shaping and sizing. A metal hammer can damage the coin.
* **Coin Ring Reduction Die Set (Optional but Helpful):** These dies help to reduce the diameter of the ring more evenly and efficiently than a mandrel alone. They are particularly useful for working with harder metals.
* **Polishing Cloths:** For cleaning and polishing the finished ring. Microfiber cloths are ideal.
* **Sandpaper:** Various grits (e.g., 220, 400, 600, 800, 1000, 2000 grit) for smoothing rough edges and removing scratches. Wet/dry sandpaper is recommended.
* **Files:** Small metal files (round, flat, half-round) for refining the shape and removing burrs.
* **Cutting Oil (Optional but Recommended):** Lubricates the drill bit and reduces friction, preventing overheating and extending the life of the bit.
* **Bench Vise:** To hold the coin securely during drilling and filing.
* **Metal Polish:** For achieving a high-shine finish.
* **Liver of Sulfur (Optional):** To create an antique or tarnished look.
* **Protective Coating (Optional):** A clear lacquer or sealant to prevent tarnishing and protect the finish.
* **Calipers or Ring Sizer:** Used to accurately measure the ring size.

## Step-by-Step Guide to Making a Coin Ring

Now that you have your coin and tools, let’s get started!

**Step 1: Safety First!**

Before you even touch a tool, put on your safety glasses and gloves. Safety is paramount when working with metal.

**Step 2: Mark the Center**

Use the center punch and a hammer to create a small indentation in the exact center of the coin. This will serve as a guide for your drill bit.

**Step 3: Drill a Pilot Hole**

Place the coin in the bench vise, ensuring it’s securely held. Use a small drill bit (e.g., 1/16 inch) to drill a pilot hole in the center of the coin, using the indentation you created as a guide. Apply cutting oil to the drill bit to keep it cool and lubricated.

**Step 4: Enlarge the Hole**

Gradually increase the size of the hole using larger drill bits. Work your way up in small increments (e.g., 1/8 inch, 1/4 inch, 3/8 inch). This prevents the drill bit from binding and reduces the risk of damaging the coin. Continue to use cutting oil.

**Step 5: Use the Step Drill Bit (Unibit)**

Once you’ve created a sufficiently large hole, switch to the step drill bit (Unibit). This will create a smooth, gradually widening hole. Carefully and slowly drill, checking the size frequently against your desired ring size. Stop when the hole is slightly smaller than the final size you want.

**Step 6: Annealing (Optional but Recommended for Harder Metals)**

If you’re working with a harder metal like copper-nickel clad, annealing can make the coin more malleable and easier to work with. To anneal the coin, heat it with a torch until it glows a dull red. Then, quench it in water. This process softens the metal.

**Step 7: Folding the Coin**

This step is crucial for shaping the coin into a ring form. There are several methods for folding the coin:

* **Using a Coin Ring Reduction Die Set:** This is the most efficient and precise method. Place the coin over the appropriate die and use a hammer and punch to gradually fold the edges inward. Rotate the coin frequently to ensure even folding.
* **Using a Doming Block and Punch:** A doming block is a metal block with a series of concave depressions. Place the coin over a depression that’s slightly smaller than the coin and use a doming punch to gently shape the coin inward. Work your way around the coin, gradually folding the edges.
* **Using Pliers and a Soft Hammer:** This method is more challenging but can be done with patience. Use pliers to gently fold small sections of the coin’s edge inward. Then, use a soft hammer (rawhide or nylon) to flatten the folded sections. Work your way around the coin, gradually folding the entire edge.

No matter which method you choose, work slowly and carefully to avoid cracking or creasing the coin. The goal is to gradually fold the edges inward until they meet in the center, creating a ring shape.

**Step 8: Shaping and Sizing on the Ring Mandrel**

Once the coin is partially folded, place it on the ring mandrel. Use a rawhide or nylon mallet to gently tap the ring down the mandrel, gradually shaping it into a round form and increasing its size. Work your way around the ring, tapping evenly to avoid distortion. Check the size frequently using calipers or a ring sizer. Continue tapping until the ring reaches your desired size.

**Step 9: Filing and Sanding**

Now it’s time to refine the shape and smooth out any rough edges. Use metal files to remove any burrs or sharp points. Start with a coarser file and gradually move to finer files. Pay particular attention to the inside and outside edges of the ring.

Next, use sandpaper to smooth the surface of the ring. Start with a coarser grit (e.g., 220 grit) and gradually move to finer grits (e.g., 400, 600, 800, 1000, 2000 grit). Wet sanding (using water with the sandpaper) can help to create a smoother finish. Be sure to sand both the inside and outside of the ring.

**Step 10: Polishing**

Once the ring is smooth, it’s time to polish it to a shine. Use a polishing cloth and metal polish to buff the ring until it gleams. You can also use a polishing wheel on a rotary tool for a faster and more consistent finish.

**Step 11: Patina or Antiquing (Optional)**

If you want to create an antique or tarnished look, you can use liver of sulfur. Mix a small amount of liver of sulfur with hot water. Dip the ring into the solution for a few seconds, or until it reaches the desired level of tarnishing. Rinse the ring with water and pat it dry. You can then use a polishing cloth to remove some of the tarnish and highlight the details of the design.

**Step 12: Protective Coating (Optional)**

To prevent tarnishing and protect the finish, you can apply a clear lacquer or sealant. Follow the manufacturer’s instructions carefully.

**Step 13: Final Inspection and Cleaning**

Give your ring a final inspection to ensure that all edges are smooth and that the finish is to your liking. Clean the ring with a soft cloth to remove any fingerprints or residue.

## Tips for Success

* **Practice Makes Perfect:** Don’t be discouraged if your first few attempts aren’t perfect. Coin ring making is a skill that improves with practice.
* **Start with Easier Coins:** Begin with softer metals like silver to get a feel for the process.
* **Go Slow and Steady:** Rushing will only lead to mistakes. Take your time and work carefully.
* **Use Plenty of Lubrication:** Cutting oil is your friend. It will help to keep your drill bits cool and prevent them from binding.
* **Don’t Be Afraid to Experiment:** Try different coins, techniques, and finishes to find what works best for you.
* **Watch Videos and Read Tutorials:** There are many excellent resources available online that can provide additional guidance and inspiration.

## Troubleshooting

* **Coin Cracking:** This is usually caused by excessive force or uneven folding. Work slowly and carefully, and make sure to anneal the coin if necessary.
* **Drill Bit Binding:** This can be caused by overheating or using too much force. Use plenty of cutting oil and drill at a slower speed.
* **Uneven Ring Shape:** This is usually caused by uneven tapping on the mandrel. Work your way around the ring, tapping evenly to avoid distortion.
* **Tarnishing:** This is a natural process that can occur over time. Clean the ring regularly with a polishing cloth, or apply a protective coating.
