How are Antique Instruments Authenticated and Appraised?

Behind the Scenes: How Violins Are Authenticated And Appraised

By John Patrick Egan Violins, Dublin

When a violin comes into our hands—whether discovered in an attic or passed down through generations—it carries more than just wood and varnish. It holds stories, craftsmanship, and sometimes, unexpected value. But how do we uncover the truth behind an instrument? Here's a behind-the-scenes look at how violins are authenticated and appraised at our Dublin workshop.

Step 1: The First Impressions

The process begins the moment we open the case. Signs of age, craftsmanship, and condition are immediately apparent to a trained eye. We observe the arching of the plates, the scroll's carving, and the varnish’s colour and wear patterns. Even the smell of the instrument can offer subtle clues.

Step 2: Examining the Label (and Looking Beyond It)

Many violins carry paper labels inside the body, often visible through the f-hole. While labels can hint at origin or maker, they’re also frequently misleading. Some were added later to increase perceived value. We treat labels as one part of a larger puzzle—not proof on their own.

Step 3: Construction and Materials

True authentication comes from examining how the instrument was built. The type of purfling (the decorative inlay around the edges), the wood grain, and the way the neck is set—all offer clues about the violin’s origin. Certain regional schools and makers left telltale signatures in their work.

Step 4: Comparative Analysis

We compare the instrument to known examples from our archive and reference collections. Photographs, auction records, and documented instruments help us place the violin within a specific tradition—whether it’s 19th-century French, German workshop, or Irish craftsmanship.

Step 5: Consultation with Experts

For particularly rare or high-value instruments, we may seek second opinions or historical verification from trusted colleagues across Europe. Authentication is often a collaborative effort in the violin world, drawing on centuries of shared expertise.

Step 6: Valuation

Once we understand what the violin is and where it comes from, we assess condition, sound quality, provenance, and market trends. A cracked back, replaced scroll, or missing original fittings can impact value. So can a well-documented history or previous ownership by a known player.

Our appraisals include a formal written valuation and, where applicable, a certificate of authenticity. Whether you're seeking insurance, planning a sale, or simply curious, a professional valuation offers peace of mind and clarity.
