Testing 1/2 oz Gold Krugerrand coin various ways including ultrasound thickness gauge
In this video I will test a 1/2 oz South Africa Krugerrand Gold Coin, using the same methodology I have used in previous videos, if you are not familiar with the use of the ultrasound thickness gauge, I will encourage you to check out my other videos to learn more about it.
The ultrasound gauge used in this video is the ET 400 Ultrasound thickness gauge by Elpidan. This video is solely meant for educational purposes only.

How to calculate the density of gold alloys or any metal alloy using a mathematical equation.
Переглядів 6 тис.3 роки тому
In this video I will explore an equation used to determine what the volume of a metal alloy should be according to the metal parts content and use this information to determine what the density of that alloy should be. A 1/2 oz 1980 South Africa Krugerrand gold coin is used to determine its volume and density (specific gravity). This coin is made up of an alloy 91.67% gold and 8.33% copper.

    I have tested coins in the same way you just did. I was just wondering if the Centenario coin will test out right when it come to being diamagnetic I know all the modern coins & bars do, but when it comes to the pre 1933 coins they don't seem to work with that test. They act as if they are paramagnetic, they must have some impurities in them. As you know I'm sure Tungsten is paramagnetic where as gold & silver & coper .... are diamagnetic... Luckily for us. I float them on water using a lid then slowly push a strong rare earth magnet towards them to see if it pushes away or draws towards it....

    Very interesting video, I'm fascinated by the pitch of the coins. Also, the method of volume measuring is brilliantly accurate. Depending on what the black things on your caliper are, your measurement will be off if you exert any pressure more than just touching the coin ;-). It seems to me, with the correct weight and shiny surface, people holding it does not account for size variation, the cheap caliper is the more likely source ;-)

    Thank you for your video. Regarding 8:48, counterfeiters have been using gold covered tungsten to make fake gold coins, because tungsten has a density which almost the same as gold which is 19.3 grams per cubic centimeter. However by using the neodymium magnet test, a genuine Gold Krugerrand suspended on a pendulum is diamagnetic and thus is slightly repelled by a neodymium magnet whereas tungsten is paramagnetic and thus is slightly attracted towards a neodymium magnet as demonstrated @ ua-cam.com/video/SgPOPozHRow/v-deo.html. Regarding 9:26, a genuine Gold Krugerrand will produce a resonating ringing sound with the acoustic ping test whereas a gold plated tungsten Fake Krugerrand will produce a dull thud sound as demonstrated @ ua-cam.com/video/boB4yyS-fDk/v-deo.html

    My 1945, 50 Pesos gold coin has a diameter: 36.85 mm and thickness: 2.60 mm, it makes a nice ping sound, and the magnet doesn't stick. The dimensions are a tiny bit low? But I believe it is real. The specification sheet says that the coin is 90% gold and 10% copper and that its density is 17.1 grams/cc. This information is used to test the coin... Test1: weigh the coin... The coin itself lists 37.5 grams of pure gold in the coin. So by mathematics the weight of the coin = 37.5/0.9 = 41.67 grams and must weigh that amount if it is authentic. Test 2: measure its volume... Its density is 17.1 gram/cc therefore the volume of the coin must be 41.67/17.1 = 2.43 cc. And you showed how to measure the coins' volume by weighing it in water--Amazing! Since water has a density of 1 gram/cc, the coins' volume was found by immersing it completely in water and that weight equals the volume of the coin. I must purchase the micro balance to be able to do tests 1 and 2 in order to further verify my coin. Thanks JC and Staff.
