Made in the USA. Coin Scanner Kit – Make Sure your Gold Krugerrands and Silver are Real not FAKES. How do you know that your Gold and Silver doesn’t contain inexpensive tungsten? Have you tested your Gold and Silver? How do you test your Gold and Silver? Our company’s high tech scanners use patented technology that capitalizes on the unique magnetic signature of gold and silver to prove that it does not contain tungsten. Tungsten is the #1 metal used to craft high quality frauds. The reasons tungsten is used is because it’s density/weight is nearly the same as gold and it’s dirt cheap. Gold’s density is 19.3 grams/cc and tungsten’s density is 19.25 grams/cc This means that counterfeiters are creating realistic coins and bars that look exactly like a real gold coins with identical weight, diameter and thickness. This bullion/coin scanner illuminates tungsten inside coins and bars. Very easy to use. Hollow Coin with Test Materials. Pelican Carrying Case (Water Proof, Shock Proof and Dust Proof). Every metal has a unique magnetic susceptibility profile. These profiles can be categorized into a magnetic ordering characteristic e. Ferromagnetic, paramagnetic and diamagnetic. Gold Lock’s Bullion Scanner capitalizes on this phenomena to detect tungsten in precious gold and silver. Ferromagnetism is the basic mechanism by which certain materials such as iron form permanent magnets. Paramagnetism is where certain materials are attracted to an external field but will not be permanently magnetized. Tungsten is as example of paramagnetic material with a strong positive magnetic susceptibility of 8.44. Diamagnetic materials create an induced magnetic flux in the opposite direction of an applied magnetic field. Diamagnetic materials are repulsed by magnetic fields. Diamagnetic force is the opposite of paramagnetic force and has a negative value. Examples of paramagnetic metals are gold (-3.44) and silver (-2.38). Metallic magnetic susceptibility values. Positive values are paramagnetic and are attracted. Negative values are diamagnetic and are repulsed. Direction of magnetic fields are also opposite in regards to whether the material is paramagnetic or diamagnetic. Positive values appear dark when viewed through the Bullion Scanner; negative values appear light. Positive values are attracted to magnetic fields; negative values are repulsed. Tungsten will appear dark in the Internal Coin Scanner even if it is concealed inside a gold coin. WHY ARE THE’GOLD LOCK’ SCANNERS NECESSARY? Gold and tungsten have nearly the same densities. Gold is 19.3 grams/cc and tungsten is 19.25 grams/cc. Counterfeiters exploit tungstens high density to mimic gold and fool unsuspecting investors. Unscrupulous gold sellers could quadruple their investment. WHAT ARE THE GOLD LOCK SCANNERS LIMITATIONS? The Internal Coin Scanner (ICS) only detects disturbances in the magnetic force e. Homogeneous mixtures of silver and copper are diamagnetic and will not create a disturbance and therefore will be magnetically sensitivity indistinguishable from gold. WHAT OTHER TESTS SHOULD A PRUDENT INVESTOR PERFORM? #1 Research specification of the test coins youd like to validate i. Weight, diameter and thickness. #2 Weigh the test coin. Use a quality scale and verify its accuracy by weighing a known authentic coin. The weight of the test coin should be within plus or minus 0.1 grams. Too light indicates that the coin metals density is too low such as silver or copper in gold coins or non-magnetic stainless steel in silver coins. Too heavy indicates that too much tungsten was used to make the fake coin. #3 Check the diameter and thickness of the test coin with a set of calipers. These measurements must match exactly. Any deviation should be considered a fraud. #4 Perform a ring test on silver coins. Drop the silver test coin on a hard surface such as a table. A silver coin possesses a clear distinctive enduring ring. A fake silver coin will give a dull thud instead of a resonating ring. Drop a real silver coin and listen to the ring. #5 Check silver coins with a neodymium rare earth magnetic slide. Silver is diamagnetic and repulses the magnetic field. A silver coin will slide very slowly but a stainless steel fake will slide fast. This product will be offered for sale to the public in the future. #6 If the composition of the test coin is still in question then an Archimedes density test should be performed. Density is measured in grams (g) per cubic centimeter (cc). First step is to weigh the target coin. Second is to place a container of water on the scale and zero/tare the scale. Third is to tape a thread onto the coin and submerge. It is important not to let the coin touch the walls or bottom of the water filled container. Record the weight while the coin is suspended in the water; this weight is the amount of water displaced. Waters density is 1.0 g/cc. To determine the density of the test coin; divide the weight of the coin by the weight of the displaced water. Densities of some precious metals and common metals used for counterfeits. Water (H2O) 1.0 g/cc. Stainless Steel approximately 7.84 g/cc. Copper (Cu) 8.96 g/cc. Silver (Au) 10.49 g/cc. Lead (Pb) 11.34 g/cc. Tungsten (W) 19.25 g/cc. Gold (Au) 19.3 g/cc. Platinum (Pt) 21.45 g/cc. Densities of common precious metal coins. Platinum Maple Leaf: 100% platinum 21.45 g/cc. Gold American Eagle: 91.67% gold, 3.00% silver, 5.33% copper 18.48 g/cc.

Silver Canadian Maple Leaf: 100% silver 10.49 g/cc. Silver Dollar: 90% silver, 10% copper 10.34 g/cc. Calculated densities from the test results should be close + or 5%. If they are not close then the test coin is a counterfeit.
