Turn a Coin into Treasure: A Step-by-Step Guide to Making a Silver Coin Ring
Crafting a ring from a silver coin is a rewarding project that combines history, artistry, and a touch of metalworking. This guide provides a comprehensive, step-by-step process to transform a common silver coin into a unique and wearable piece of jewelry. Whether you’re a seasoned hobbyist or a curious beginner, this project offers a fascinating glimpse into the world of coin ring making.
Before we begin, let’s address a common question: Is it legal to make rings out of coins? In most places, it is legal to deface or alter currency *unless* you intend to use the altered currency as real money. Since the purpose is to create jewelry, and not to defraud anyone, it’s generally permissible. However, it’s always best to check local laws and regulations if you have any concerns.
What You’ll Need
To embark on this exciting project, you’ll need a few essential tools and materials:
* **Silver Coin:** The star of the show! Morgan Silver Dollars, Peace Dollars, or 90% silver US dimes, quarters, and half dollars are popular choices due to their silver content and size. Look for coins in circulated condition, as uncirculated coins are more valuable and altering them might be considered undesirable by collectors. A circulated coin will also likely be cheaper.
* **Ring Sizing Mandrel:** A tapered steel rod used to shape and size the ring. Get one made of hardened steel.
* **Hammer (Ball-peen or other):** For shaping and hammering the coin around the mandrel.
* **Protective Glasses:** Safety first! Protect your eyes from flying debris and metal shards.
* **Ear Plugs or Hearing Protection:** This project can get noisy, so protect your ears.
* **Drill Press or Hand Drill:** To create the initial hole in the center of the coin. A drill press offers greater precision.
* **Drill Bits:** A variety of sizes, including a pilot drill bit and a larger bit to create a substantial hole for starting the ring forming process. High-speed steel (HSS) bits are recommended.
* **Coin Ring Reduction Die Set (Optional but Recommended):** This specialized tool helps reduce the diameter of the ring evenly and efficiently. It greatly improves the appearance and final quality of the ring.
* **Soft Metal Hammer (Nylon, Brass, or Delrin):** Used with the reduction die to avoid damaging the coin.
* **Annealing Torch (Propane or Butane):** To soften the silver and make it easier to work with. A small handheld torch is sufficient.
* **Heat-Resistant Surface:** A fire brick or similar surface to protect your work area while annealing.
* **Water Bucket:** For quenching the hot coin after annealing.
* **File Set:** For smoothing rough edges and refining the shape of the ring.
* **Sandpaper (Various Grits):** To polish the ring and achieve a smooth, professional finish.
* **Polishing Compound and Cloth:** For final polishing and bringing out the shine of the silver.
* **Gloves:** To protect your hands during the hammering and polishing processes.
* **Sharpie or Marker:** For marking the center of the coin.
* **Calipers or Ruler:** To measure the coin’s dimensions and mark the center precisely.
* **Cutting Oil or Lubricant:** To cool the drill bit and prevent overheating during drilling.
* **Safety Mask:** To avoid breathing in metal particles during sanding and polishing.
* **Liver of Sulfur (Optional):** For creating a patina or darkened effect on the ring, highlighting the details of the coin.
* **Baking Soda (Optional):** For neutralizing the liver of sulfur.
Step-by-Step Instructions
Now, let’s get started! Follow these steps carefully to create your own stunning silver coin ring:
**Step 1: Preparation and Safety**
* **Clear your workspace:** Ensure you have ample room to work and that your area is well-lit.
* **Gather all your tools and materials:** Having everything within reach will streamline the process.
* **Put on your safety glasses and earplugs:** Protecting your eyes and ears is paramount.
**Step 2: Identifying the Coin and Determining Ring Size**
* **Choose your coin:** Select a silver coin that is in good enough condition to handle the process but not so good you’ll feel guilty altering it. A Morgan or Peace Silver Dollar is a common and excellent choice. Smaller denomination 90% silver coins can also work.
* **Determine your ring size:** Use a ring sizing chart or mandrel to find the desired size. Consider that the coin ring will be thicker than a standard ring, so you might need to go up half a size.
**Step 3: Marking the Center of the Coin**
* **Find the exact center:** Use calipers or a ruler to measure the diameter of the coin. Divide the diameter by two to find the radius.
* **Mark the center:** Use a Sharpie or marker to mark the exact center of the coin. Precision is crucial for a well-balanced ring.
**Step 4: Drilling the Initial Hole**
* **Set up the drill press (or hand drill):** Secure the coin in a vise or clamping device to prevent it from spinning during drilling. If using a hand drill, hold the coin firmly and steady it.
* **Pilot hole:** Start with a small pilot drill bit to create a guide hole. This will prevent the larger bit from wandering.
* **Larger hole:** Gradually increase the size of the drill bit until you have a hole large enough to start the ring forming process. A general starting point is around 1/4 to 3/8 inch, but it depends on the size of the coin and the desired ring size. Don’t go too big too soon; you can always make the hole larger later.
* **Use cutting oil:** Apply cutting oil or lubricant to the drill bit and the coin to keep them cool and prevent overheating. This also helps prolong the life of your drill bits.
* **Drill slowly and steadily:** Apply consistent pressure and avoid forcing the drill bit. Let the bit do the work.
**Step 5: Annealing the Coin (Softening the Silver)**
* **Place the coin on a heat-resistant surface:** A fire brick is ideal.
* **Heat the coin evenly:** Using the annealing torch, heat the coin evenly until it glows a dull red color. This process softens the silver, making it more pliable.
* **Quench the coin:** Carefully pick up the hot coin with tongs and immediately quench it in the bucket of water. This rapid cooling helps to further soften the silver. Note that this step can produce steam.
**Step 6: Reducing the Coin’s Diameter (Using a Reduction Die)**
* **Position the coin:** Place the annealed coin into the appropriate sized reduction die.
* **Hammer Carefully:** Using a soft metal hammer (nylon, brass, or delrin), gently hammer the coin through the reduction die. Work in small increments, rotating the coin frequently to ensure even reduction.
* **Repeat as needed:** Continue hammering and rotating the coin through progressively smaller reduction dies until the coin begins to take a noticeable ring shape and the diameter is closer to your desired ring size.
**Step 7: Shaping the Ring on a Mandrel**
* **Place the partially formed ring on the ring mandrel:** Slide the coin onto the mandrel with the design facing the direction you want on the final ring.
* **Hammer the ring down:** Using a hammer, carefully tap the outside edge of the coin (now partially formed ring) working around the circumference, gradually pushing it down the mandrel. Work slowly and evenly to maintain a round shape. Rotate the ring frequently.
* **Re-anneal as needed:** If the silver becomes too hard to work with, repeat the annealing process (Step 5). Annealing may be necessary several times during the shaping process.
* **Continue shaping:** Continue hammering and rotating until the ring reaches the desired size on the mandrel. Periodically check the size with a ring sizer.
**Step 8: Refining the Shape and Size (Using a File)**
* **File the edges:** Use a file to smooth any rough edges or imperfections on the ring. Pay close attention to the inside and outside edges.
* **Refine the shape:** Continue filing to achieve a perfectly round and uniform shape. Use the mandrel as a guide.
**Step 9: Sanding and Polishing**
* **Start with coarser grit sandpaper:** Begin with a lower grit sandpaper (e.g., 220 grit) to remove any scratches or imperfections from filing.
* **Progress to finer grits:** Gradually move to finer grits of sandpaper (e.g., 400, 600, 800, 1000, 1500, 2000) to smooth the surface of the ring.
* **Wet sanding:** Wet sanding with water or mineral oil helps to prevent the sandpaper from clogging and produces a smoother finish.
* **Polish the ring:** Apply polishing compound to a soft cloth and polish the ring until it shines. A polishing wheel or Dremel tool with a polishing attachment can also be used.
**Step 10: Adding a Patina (Optional)**
* **Prepare the liver of sulfur solution:** Mix a small amount of liver of sulfur with hot water. Follow the instructions on the liver of sulfur package.
* **Apply the solution:** Submerge the ring in the liver of sulfur solution for a short period of time (a few seconds to a few minutes), until it reaches the desired level of darkness. Monitor the color change closely.
* **Neutralize the solution:** Remove the ring from the liver of sulfur solution and immediately rinse it with water. Then, submerge it in a baking soda solution to neutralize the acid.
* **Polish the raised areas:** Use a polishing cloth or wheel to polish the raised areas of the ring, removing the patina and highlighting the details of the coin design. This will create a beautiful contrast between the dark recesses and the bright, polished surfaces.
**Step 11: Final Polishing and Cleaning**
* **Final polish:** Give the ring a final polish with a clean polishing cloth to remove any remaining residue and enhance the shine.
* **Clean the ring:** Wash the ring with soap and water to remove any remaining polishing compound or other debris.
* **Dry the ring:** Thoroughly dry the ring with a soft cloth.
**Tips and Considerations**
* **Patience is key:** Making a coin ring takes time and patience. Don’t rush the process, and be prepared to repeat steps as needed.
* **Practice makes perfect:** Your first coin ring may not be perfect, but with practice, you’ll improve your technique and create stunning results.
* **Coin Selection:** Experiment with different coins to find the ones you like best. Different coin designs and silver content can affect the final look of the ring.
* **Tool Maintenance:** Keep your tools clean and well-maintained to ensure optimal performance and longevity.
* **Safety First:** Always prioritize safety when working with tools and heat. Wear appropriate safety gear and follow all safety precautions.
* **Customize your ring:** Get creative with your designs! You can add textures, engravings, or other embellishments to make your coin ring truly unique.
