Product Information

Due to popular demand, we are now offering the Precious Metal Verifier as a special order item.  Please allow up to 6 weeks from the payment date for your order to ship.

Please note: for international orders, the PMV must be ordered by itself.  It cannot be combined with other items.

We are in the process of working on additional demonstrations and resources for this new device.  In the meantime, please contact the manufacturer directly with questions about functionality.

 The Precious Metal Verifier is a powerful new tool in counterfeit detection.  The PMV can test a wide range of coins and bars in just seconds without the use of chemicals or methods that could damage the item in question.  The PMV can read through coin flips and plastic bags, and for coins roughly 1/4 oz and larger, it can also read through numismatic slabs.

Using electromagetic waves, the PMV reads electrical properties of the underlying metal and compares the results to a database of known values.  It displays the results in the simple format of brackets, representing the range of expected values for the selected metal, and a black box, representing the reading for the piece being tested.

     

When the box falls inside the brackets, the electrical properties of the piece being tested are within the expected range of values.  If the box falls slightly outside of the brackets, the piece should be thoroughly examined and subjected to additional testing to verify authenticity.  If the box falls far outside the brackets, it is likely not made of the expected metal.

The PMV ships with the following metals in the database:

Gold - Pure
Gold - 91.7% 22K Crown
Gold - 90%
Gold - American Eagle
Gold - 98.6%
Silver - 99.99% Pure
Silver - 99.9% Pure
Silver - 92.5% Sterling
Silver - Morgan Dollar
Silver - Peace Dollar
Silver - 90% Coin
Silver - 96% Britannia
Platinum
Palladium
Rhodium
Copper

If and when additional metals are added to the database, the PMV can be updated using the included USB charging cable and a PC.  Updates are released on the manufacturer's website.

The PMV has a sensor built into the main unit for larger coins and bars loose or in plastic flips or bags, and larger coins (approximately 1 ounce and greater) in numismatic slabs.  The large wand can test smaller coins and bars (approximately 1/4 ounce and greater) loose, in plastic flips or bags, or in numismatic slabs.  The small wand can test fractional pieces loose or in thin plastic bags.

The Basic Kit includes the PMV, small wand, large wand, USB charger, calibration disk, and carrying case.

The Bullion Kit includes the PMV, small wand, large wand, bullion wand, USB charger, calibration disk, and carrying case.

The bullion wand penetrates four times deeper than the other sensors, which is great for larger bars and poured bars with heavy surface textures or stamping.

Please note that the Precious Metal Verifier is a powerful tool, but like any tool, you must use it properly to acheive the desired results and recognize its limitations.  Here are a few tips for getting the most out of your investment.

Sensor Selection

 Be sure to reference the Sensor Selection Chart (PDF) and use the appropriate sensor for the item you are testing.  The test item must cover the face of the sensor completely for an accurate reading.  That means covering the entire face of the wand or covering the circle printed on the platform of the main unit.  Testing an item that is too small or thin for the sensor to read properly will skew the results.  Also consult the chart to see if the calibration disk is required for the item you are testing.

90% Coin Silver

Due to the nature of the "junk silver" alloy and the tendency for there to be impurities in the non-silver 10% balance of the alloy, 90% silver coins will often read slightly outside of the brackets on the 90% Coin Silver setting, especially for coins made in the 1950s and earlier.  While the alloy is nominally 90% silver and 10% copper, some coins have a trace amount of lead and/or tin in the non-silver 10% balance, which affects the electrical properties of the alloy and therefore the reading taken by the PMV.  You can test other 90% coins using the Peace Dollar setting, which is a slightly wider range due to the impurities being more common in those coins.  It is also worth noting that all of the genuine 90% coins we have tested, while sometimes reading outside of the brackets on the 90% Coin Silver setting, have tested with the block somewhere on the screen.  All of the counterfeit 90% coins we have tested have resulted in a left or right arrow, indicating a measurement far outside of the expected range.

 Copper Alloys

Certain copper alloys can mimic the electrical properties of gold and silver.  In these cases the PMV may display a result that falls within the expected range for gold or silver, even though the metal is not gold or silver.  Since a copper alloy is less dense than silver or gold, counterfeit pieces made of such an alloy will either be under the expected weight or over the expected size.  For this reason it is always recommended that the weight and dimensions also be checked.  We have encountered a few counterfeit gold pieces using a gold-plated copper alloy that tested as pure gold on the PMV, but they are either under weight or thicker than they should be.  For silver bars and rounds, we recommend first testing on the 99.99% Pure Silver setting, as most commercially pure silver (.999) will fall within the brackets on this setting while most copper alloys will not.  If your .999 silver falls slightly outside the brackets on the 99.99% Pure setting, then use the 99.9% setting and also check the dimensions and weight.

 Tilting Wands and Surface Textures

The PMV uses a circulating current to measure the electrical properties of the underlying metal in the piece you are testing.  If there is a gap between the sensor and the metal (such as a numismatic slab or plastic flip), it must be consistent across the entire face of the sensor.  If the gap is not consistent (for instance, if you tilt the wand instead of keeping it flat on the surface of the metal), the reading will not be accurate.  A rough surface texture or deep stamping, often present on poured silver bars, can similarly affect the reading.  The bullion wand is recommended for those instances, as it reads deeper into the metal and can overcome some of those surface obstacles. 

Temperature

An extremely cold sample may read slightly left, and an extremely hot sample may read slightly right.  The PMV is calibrated to test samples at room temperature.
