There is great value in avoiding any damage to a collectable coin during assessment as this may diminish its value by thousands of dollars in certain cases. X-ray fluorescence (XRF) analyzers provide a fast, accurate, and most importantly, nondestructive alternative for assessing the metal composition of coins, and are currently used by numismatic professionals (those who study and collect coins and other currency). Here are a few examples of how XRF can be used to detect numismatic fraud and increase the operational speed and efficiency for coin collectors and dealers.
VERIFICATION OF ELEMENTAL COMPOSITION
Many coin series are characterized by a unique elemental signature, meaning that the amount and type of certain metals are clearly defined. Any deviation from this composition would indicate fraud. Mid-year changes in precious metal content would be detected by XRF

BULK ANALYSIS OF COINS
Analyzing each and every coin by examining its mint year can be a tedious, eye-constraining, distracting, and time-consuming task. With the help of portable XRF, this task can be reduced to a fraction of the time — without having to remove the coins from the wrappers or bags in which they were delivered. 

GOLD PLATING DETECTION

Purity levels can vary up to 22K. In addition, they can come in gold (Au)-plated or un-plated versions – which are difficult to distinguish. Some XRF instruments contain patented detection technology that detects gold plating by applying primary and direct tests. Fake coins are flooding the
markets! • The methods used by counterfeiters are becoming more and more advanced. • A common method to fake coins is to apply a silver plating
to a non-silver substrate, in an effort to imitate a solid silver coin.

FRAUD DETECTION
Portable XRF analyzers can easily detect the composition of the coin, revealing any deviations from the original coin’s known composition. 

DIRECT MEASUREMENT OF ENCAPSULATED COINS
Valuable coins are often protected by thin foils or encapsulated in plastic slabs and removing those protective covers instantly diminishes the value. Counterfeiters often enclose a fake coin in a protective sheet, assuming and hoping that the buyer is not likely to open it. Portable XRF can easily detect the composition of the coin by testing through thin foil covers, and provide a very good indication of the coin’s composition even in the case
of thicker plastic slabs.

Don’t Waste a Precious Minute

For buyers of scrap gold jewelry, gold-plated pieces present significant challenges and can adversely affect profitability. We can help you meet that challenge – accurately and easily – with  Au Detection & Identification Technology (AuDIT™). AuDIT is a proprietary plating detection technology developed for, and only available on,  portable x-ray fluorescence (XRF) analyzers, including the  ND88  precious metal analyzers. This breakthrough software feature comes standard on any of our handheld or desktop analyzers that are calibrated for precious metals analysis. Several independent, complementary methods in the software work in tandem to alert you to the probability that an item is plated.

Quickly Detect Gold Plating

The primary patent-pending technology is used as the first test for gold-plated items. If this test fails, you can be relatively certain that the items are, in fact, plated. This method works regardless of the gold concentration of the plated surface layer. If this initial test fails, “Gold Plate Probable” is displayed and highlighted on the screen.

Other tests are conducted
simultaneously to warn users that something is “off” in the analysis of the sample. These are considered secondary tests and will warn you only if the initial test passes. These tests include, but may not be limited to, the following: 1. High nickel (Ni) content, which can indicate presence of a Ni boundary layer between the substrate and plated surface 2. Low karat values 3. Non-standard karat values (readings significantly different than, 9, 10, 14, 18, 22, and 24 karat gold)

Rapidly Recover Your Investment

With daily changes in the prices of precious metals, small inaccuracies in testing can significantly affect your bottom line. Accurate and reliable results remove variability in determining the value of sample items and ensure a fair transaction. Screen jewelry for toxic substances such as lead and cadmium or measure coating thickness for known plated materials to maintain quality control of your process. Whether you are in the business of buying and selling or refining and manufacturing precious metals, a analyzer will positively affect your profitability by accurately identifying precious metal compositions. Purchasing one of our analyzers is a sound investment decision. A simple payback calculation shows that even modest jewelry transactions of about one troy ounce per day will result in a payback period of one year or less. Make the investment today and earn the return.

Fast. Accurate. Non-destructive.

With x-ray fluorescence (XRF) precious
metal analyzers deliver reliable results at every stage of the precious metal life cycle. analyzers provide lab-quality performance in a simple, easy-to-use format. Non-destructive, simultaneous analysis of all precious metals ensures results are more comprehensive than fire assay, with comparable accuracy, and eliminate the toxicity associated with nitric acid methods. Test results appear in seconds.

While fire assay is widely used and considered to be one of the most accurate methods to  etermine the gold content in jewelry, it requires a destructive, multi-step process that separates gold from all the other metals in a sample. Skilled precision is required. In comparison, our  analyzers determine the exact karat weight and percentages of the gold present in a sample, simultaneously testing all precious metals along with common alloying elements. Get reliable
results without altering samples. Minimal training is required. Simple and fast, XRF results are
• Typically within 1/8 of a karat of fire assay • More comprehensive than fire assay • More accurate than other on-site testing methods such as nitric acid scratch tests • Free of hazardous chemicals
• Unaffected by subjective analysis and multi-step processes

The price of a solid gold bracelet is significantly more than a gold plated bracelet, yet it can be challenging to determine the difference. With the simple touch of a button or pull of a trigger, you can rapidly and reliably determine the presence of gold plating on a non-gold substrate. While limited to the thickness of gold typically used in the jewelry industry to plate items, technology accurately confirms the presence of • Vermeil (gold-plated silver) • Gold-plated copper • Steel • Tungsten • Any other non-gold substrates Our precious metal analyzers offer a patented solution for detecting gold plating • A primary, direct test measures the energy levels of fluorescence x-rays coming from the plating and substrate • Secondary, indirect tests simultaneously warn of the presence of gold plating by confirming - High nickel (Ni) content - Low karat values - Non-standard karat values

Periodic table of elements

How XRF Analysis Works

How XRF Analysis Works

1. X-rays are produced by the analyzer and pointed at a sample surface.

2. The energy causes inner-shell electrons to be ejected.

3. Outer-shell electrons fill the vacancies left by the ejected electrons and fluorescent x-rays are emitted.

4. The fluorescent x-rays enter the detector and send electronic pulses to the preamp.

5. The preamp amplifies the signals and sends them to the Digital Signal Processor (DSP).

6. The DSP collects and digitizes the x-ray events and sends the spectral data to the main CPU for processing.

7. The CPU analyzes the spectral data to produce detailed composition analysis.

8. Composition data and other grade or value identification are displayed and stored in memory for later recall or download to an external PC.
