From tarnished relic to treasured display: Restoring Knights Templar coins
The first commandment of restoration: Do no harm
To hold a Knights Templar coin is to hold a tangible piece of a legend. These small metal discs, often simple deniers or oboles, passed through the hands of knights, pilgrims, and merchants centuries ago. They funded crusades, built fortifications, and powered one of the most formidable organizations of the Middle Ages. Yet, when unearthed after centuries of slumber, their stories are often obscured by a thick layer of dirt, grime, and corrosion. The immediate impulse for any enthusiastic collector is to scrub away the centuries and reveal the crisp cross pattée or the stylized temple beneath. But this is where the journey of a true custodian begins, and the first rule is paramount: do no harm.
Before a single drop of water touches your artifact, a period of careful assessment is crucial. The goal is not to create a shiny, new-looking coin; it is to stabilize the artifact and reveal its details without erasing the history etched into its surface by time itself. This history often manifests as patina, the thin layer of oxidation that forms on metal over long periods. On silver coins, it can be a dark, attractive toning. On bronze or copper, it can be a smooth green or brown layer. This patina is not dirt; it is a protective seal and a testament to the coin’s age and authenticity. Aggressively removing it is akin to ripping a page out of a history book—it can catastrophically devalue the coin both monetarily and historically.
Your first task is identification. Try to determine the coin’s origin, metal, and potential era. Is it a silver denier from the County of Tripoli, or a bronze coin issued under a specific Grand Master? Common Templar symbols, like the two knights on one horse or the cross pattée, are key indicators. Examining online databases, numismatic forums, and reference books can provide invaluable clues. This step is not just for curiosity; the coin’s metal composition will dictate the safest cleaning methods. What works for a stable silver coin could destroy a fragile bronze one.
Next, assess the ‘damage’ under a magnifying glass. Differentiate between loose surface dirt, hardened encrustations, and active corrosion. The most dangerous of these is bronze disease—a bright, powdery green corrosion that will actively eat away at the metal if left untreated. If you suspect bronze disease, it is often best to isolate the coin from others and seek professional advice. For most other finds, the accretions are simply the earth they rested in. Your toolkit for this delicate work should be simple and non-abrasive. Gather distilled water (tap water contains minerals that can react with the metal), a few soft-bristled brushes (a child’s toothbrush or a paintbrush with its bristles cut short works well), wooden or bamboo toothpicks for delicate mechanical cleaning, and pure olive oil. Crucially, leave the harsh chemicals, wire brushes, metal polish, and power tools on the shelf. These are the enemies of preservation.
The patient art of gentle cleaning
With your tools gathered and your coin assessed, the process of cleaning can begin. This is not a task to be rushed in an afternoon. It is a slow, methodical practice that requires immense patience, sometimes taking weeks or even months. The most powerful tool at your disposal is time.
Your first and safest step is a long soak in distilled water. Place the coin in a small, clearly labeled container and cover it completely with distilled water. Change the water every day or two. You will notice the water becoming cloudy as loose dirt and minerals dissolve away. After a week or so, you can begin the next phase. Remove the coin from its bath and, while it is still wet, gently brush it with your softest brush. Do not scrub. Use a light, circular motion to see if any of the softened dirt lifts away. If you encounter a stubborn patch of dirt, you can use a sharpened wooden toothpick to gently pick at it. Wood is softer than the metal, minimizing the risk of scratching the surface. After a brief session of gentle cleaning, return the coin to its bath of fresh distilled water. Repeat this cycle of soaking and gentle brushing over many days or weeks. Patience will reward you as layers of dirt gradually give way, revealing the details beneath without damaging the precious patina.
For more stubborn encrustations, particularly on bronze coins, the olive oil method is a time-honored technique. Submerging a coin in a bath of pure olive oil can, over a very long period, soften hardened earthen deposits. As with the water method, this requires patience. The coin may need to soak for a month or more, with occasional removal for a gentle brushing to test your progress. Once you are satisfied, you will need to remove the residual oil by soaking the coin in acetone or isopropyl alcohol for a short time, followed by a final rinse in distilled water.
Throughout this process, the most important skill to learn is knowing when to stop. The objective is legibility, not a mirror finish. Once the main designs, inscriptions, and symbols are clear, your work is likely done. Many beautiful and valuable ancient coins retain patches of dirt and color in their recesses, which adds to their character and aesthetic appeal. Over-cleaning is an irreversible mistake that strips a coin of its historical context. The goal is to be a conservator, not a polisher, preserving the silent story the coin has to tell.
From restored relic to cherished centerpiece
Once your Templar coin is cleaned, stabilized, and completely dry, the final and most rewarding step is to prepare it for display. A historical artifact of this significance should not be relegated to a dusty drawer or a simple plastic flip. It deserves to be presented in a way that honors its journey and allows its story to be told. Proper display is not just about aesthetics; it is also the final stage of preservation.
Before framing or mounting, consider applying a protective coating. A microcrystalline wax, such as Renaissance Wax, is used by museums worldwide. Applied sparingly with a soft cloth and buffed to a clear finish, it creates an invisible, breathable barrier that protects the coin from humidity, fingerprints, and environmental pollutants without altering its appearance. This simple step can safeguard your treasure for generations to come.
Now, think beyond the standard collector’s album. To truly create a display worthy of a Templar find, you must provide context. A shadow box is an excellent option. You can mount the coin on an archival-quality, acid-free backing of a suitable color—perhaps a deep crimson or an earthy linen that evokes the period. Alongside the coin, include a small, professionally printed card detailing its identification, approximate date, and a brief history of its origin. You could even add a small map highlighting the region where it was minted or a drawing of the Templar cross that appears on its face. This transforms a single object into a miniature museum exhibit.
Another modern and striking option is a ‘floating frame’. These frames consist of two panes of glass or transparent flexible plastic that press together, suspending the coin in mid-air. This allows for a 360-degree view of the artifact and creates a dramatic, minimalist presentation that draws the eye directly to the coin itself. For a more substantial feel, consider a custom-made stand or a small, easel-like mount that can sit on a bookshelf or desk. Place it alongside relevant books on the Knights Templar or a replica of a Templar helmet to create a powerful thematic display.
Finally, consider the environment. Just as you took care in its restoration, take care in its placement. Avoid areas with high humidity or drastic temperature fluctuations. Most importantly, keep the display out of direct sunlight, as prolonged UV exposure can degrade the coin’s surface over time. Use soft, indirect lighting from a nearby lamp to highlight the subtle contours and details you worked so patiently to reveal. By carefully cleaning, preserving, and thoughtfully displaying your Templar coin, you do more than just own an old object. You become the keeper of its flame, ensuring that this small, metal witness to one of history’s most fascinating chapters continues to share its legend for all to see.
