PMV PRO Coin Testing | CATCHING COUNTERFEITS AND FAKES 

Thank you for an extensive process with the machine. It gives us more knowledge and awareness how to use it properly and to practice good practices. This video was very helpful. Thank you.

I have the Sigma Pro. I’m a coin collector and stacker. The two most interesting fakes I have found are not what you would expect. One was a 1/20 oz Libertad (gold plated tungsten) and a small ancient gold coin that was too pure (9999 fine) so not genuine.

Such great info in this video, thank you so much !

Would like to see the fakes cut in half to see cross section.

The texture in the leaf on that fake Maple looks off. I’ve been pretty confident in my ability to detect a fake maple from sight alone, but this will soon be put to the test when my Sigma arrives and I test my collection. Feeling a little nervous after watching this video. 😅

How are you able to get a reliable resistivity reading through the thick vinyl sleeves and hard plastic case?

Unfortunately you did not have one that tested with the arrow in the green but the arrow's color is red. And only on the top not on the bottom.

The fake silver Maple Leaf could be a Pb-Sn alloy (lead-tin). The fake gold Maple Leaf would be Wolfram (Tungsten), my guess.

Any idea about wait times for your Pro product? I notice that it's out of stock on your website as I type this. Is there any way to register for email updates to get notified once they become available?

Can you test 10oz bars without bridge on the pro? Thanks

21:53 The Silver Bar shows the Blue Arrows in the middle of the Yellow. Is that an indicator that it could be counterfeit? Should they be in the Green Zone? What do the numbers to the right of the Blue Arrows indicate?

Question about sizing. When entering the weight, do we enter the weight of the actual piece or do we enter the weight the piece is supposed to be (if there is a descrepancy in those numbers)?

Could you explain why the shown numbers for diameter and thickness are way off? My unit shows pretty much the same numbers as yours, but thickness and diameter as shown on the LCD are off compared to the correct specs for a Krugerrand and Maple Leaf. The LCD shows around 2mm in diameter and 0.2mm in thickness difference compared to the real dimensions of the coin. Check for yourself in your video compared to the published and caliper measured numbers.

so why not make the device board wide enough to take bars?

Don't forget to calculate the density AND test with ultrasound too ! The electric conductivity test alone is not conclusive !

I don't understand what you are doing with the size test. It is never explained what is being done with the green line, etc.
