How Can I Tell if it's Silver or Silver Plated?

In the world of antiques, the line between silver and silver-plated can be deceptively thin. As dealers, we’ve all seen it—the moment someone brings in a cherished piece, convinced it’s solid silver, only for a closer examination to reveal otherwise. It’s an easy mistake to make; after all, silver-plated items were crafted to mimic their solid counterparts, often with impressive skill. But understanding the difference is essential, not just for assessing value but for appreciating the craftsmanship and context of each piece. Allow me to share the most reliable methods of identification, each with its own advantages and pitfalls, to help you discern the genuine article from its plated counterpart. You can, of course, reach out to DC Silver (www.dcsilver.com) for guidance about specific items.

1. Hallmark Examination

Method: Look for hallmarks or stamps. Sterling silver often bears marks like "925" or "Sterling," while plated items might carry terms such as "EPNS" (Electroplated Nickel Silver) or "Silverplate."

  • Pros: Non-invasive; highly reliable if the marks are legible and authentic.
  • Cons: Fakes and worn marks can mislead; some country marks can be obscure. Not all solid silver is marked at all.

2. Nitric Acid Testing

Method: Apply a silver-testing acid in a discreet area. Solid silver reacts distinctly compared to plated metals.

  • Pros: Highly accurate when done properly.
  • Cons: Requires skill and good judgment. Acid can scar silver if used improperly

3. Ultrasound or XRF Analysis

Method: High-tech approaches like X-ray fluorescence (XRF) precisely identify the metal’s composition.

  • Pros: Accurate and non-invasive.
  • Cons: Expensive and not easily accessible for casual collectors. XRF only penetrates so many microns into silver, so heavily plated items can give false readings.

4. Scratch Test

Method: Lightly scratch the surface in an inconspicuous area to see if a base metal is revealed.

  • Pros: Straightforward and effective.
  • Cons: Causes damage; unsuitable for valuable or antique pieces.

5. Magnet Test

Method: Use a magnet. Solid silver is non-magnetic, while plated items may use magnetic base metals like steel or nickel.

  • Pros: Quick, cheap, and non-invasive. Good for scanning a pile of jewelry.
  • Cons: Some plated items use non-magnetic metals, leading to false positives. 

6. Weight Comparison

Method: You can conduct a specific gravity test on silver.

  • Pros: Non-invasive and useful for experienced dealers.
  • Cons: Technically can be complicated for some

7. Conductivity Test

Method: Test the thermal or electrical conductivity of the piece. Silver is an excellent conductor compared to most base metals.

  • Pros: Scientific and non-damaging.
  • Cons: Requires specialized equipment and expertise.

Words of Wisdom

Each method has its place, depending on the piece and the stakes. For the novice, hallmarks and a good loupe are your best starting tools. But remember, even the best techniques can falter in the face of clever forgeries. Approach every new piece with both curiosity and caution—solid silver has a story worth preserving, and part of that story lies in knowing it for what it truly is.

Cleaning Out Estate and Found a Silver Collection.. What Should I Do?

A typical silver collection. It happens all the time. Mom and Dad pass away and you never asked all the questions you should have about the silver and other antiques in the house. What can you do? What should you do? People around the world are faced with these questions every single day. Before you take those items to a charity shop, there are some things you should and should not do. Lots of places are happy to look at your silver and there are pros and cons to each. Clean-out companies : Many of these companies are predatory, charging families hundreds to haul away their junk-- as well as their priceless antiques and silver. I always think this is the worst option, but sometimes when all the family is far away, this may be the best option. Just know, if they spot a gold coin collection or a midcentury Rolex in the mix, it's gone baby gone. And it would have paid for your plane ticket around the world to be more responsible. Appraisers : Appraisers are useful, but you ...

The Power of Silver Hallmarks

Hallmarks can be extremely powerful and important in silver.  They tell the story of many pieces of silver that is absent on most other kinds of antiques.  For the furniture enthusiast, there are sometimes paper labels or pencil mark signatures, but these are rare.  For silver, the marks are often there, and when they are, you need to pay heed.  The absence of a hallmark can also be significant but we'll get into that later.  In this little article, I want to describe the non-US hallmarks that have been the most important to me in my business dealings.  The photos are pieces I have bought and/or sold some of which are still available at Crescent City Connection in my silver section .  I make a description of some of these marks and use many thematically similar pieces to give those descriptions.  I don't claim these are the best of the best pieces, just items I've been able to trade. For me, at my current stage of collecting, nothing could be w...

The Box Project

About ten years ago, on a weekend trip to Staunton, VA, I was browsing around in an antique shop called The Jolly Roger Haggle Shop.  On a bottom shelf, way in the back, I thought I spotted something.  It was a very old looking box and was in terrible condition.  The entire box seemed to be covered in pine sap or some other sticky, grimy substance.  Inside, the box was lined in blue silk and had an oval mirror in the lid.  I licked my thumb and rubbed it across the lid.  The lid was inlaid with small squares, and once I wiped away some grime, I immediately recognized that the inlay I had cleaned was tortoise shell.  Although it was in terrible condition, I wanted it.  No price, of course.  So, I took it up to the front counter and inquired.  "Where did you find that?"  The owner asked. "It was over there on the shelf gathering dust.  What do you want on it?"  I replied. The man said he would take $20.  I f...
