A FAKE GOLD BUFFALO HOW TO SPOT IT and How We Know for Sure! 

It wasn't that bad. Calm down. It was a watchable video

Yes, the krugerrand does not even look like gold.

The original St Gaudens $20 coin was 90% gold and 10% copper. Perhaps he thought this modern version is the same?

@@artboston4787 Maybe so.

Working on it, New videos with a tripod from now on for you!!! ;)

@@CommercialRareCoins overhead tripod. I got one and they are awesome for yt videos

Sorry very windy that day ;)

How to tell when gold and tungsten alloy is introduced with 25% or so integrated in the coin?

​@@israelt.3739 Thank you for your question. Fake gold coins are not typically made from gold combined with only 25% tungsten, because they would fail the specific gravity test. Instead fake gold coins are typically made from a mostly tungsten core with a layer of gold on the surface. The first step of detection is to weigh a dubious gold coin to measure its grams. The next step is to use calipers to measure the coin's diameter and thickness. Then compare its measured diameter and thickness to known specifications for that coin. If only 25% tungsten were used in the coin, then the coin's diameter or thickness will be wider or thicker than the required specifications. Furthermore, by measuring the diameter and thickness of a coin, then its volume can be calculated for cubic centimeters. Then divide the coin's weight in grams by its volume in cubic centimeters. Weight divided by volume equals the density of the metal. If the dubious gold coin does not have a density of 19.3 grams per cubic centimeter, then it is not mostly gold or tungsten. The next test is to perform the pinging sound acoustic test. A gold coin will produce a resonating pinging sound whereas a tungsten coin will produce a dull sound or a thud.

@@jadenephrite Dear Jade. Specific gravity of Tungsten is all most identical to gold..Therefore will not show on the volume /weight test..

@@israelt.3739 It is true that tungsten has almost the same density as gold which is 19.3 grams per cubic centimeter. Therefore two other quick tests can distinguish tungsten from gold. With the pinging sound acoustic test, a gold coin will produce a resonating pinging sound whereas a tungsten coin will produce a dull sound or a thud. The next test is with a neodymium magnet. Since Gold is diamagnetic, the neodymium magnet will be slightly repelled whereas Tungsten is paramagnetic and the neodymium magnet will be slightly attracted towards.

@@jadenephrite Thickness tests can be off if a Gold Buffalo planchet was struck too hard (or slightly off) on one side and made one side of the coin a hair or two thinner than the other side. Pure gold is soft, it happens. I've seen genuine Buffalos with the thicknesses off on opposite sides of the coin due to a slightly off strike.

So what causes items to fall? Also specific gravity is a real measurement density and specific gravity are two different things

Google says there is density or specific gravity. Nothing about specific density. Things fall to the ground because time slows down near masses.

We get it...don't we Peter? ;)

Specific gravity is the scientifically correct terminology.

density and boyoncy explains the world no magic gavity needed fellow FE

Weight is the main component. If it measures 1 Troy exactly or a touch over should be fine. then do a ring test and visual inspection. Should be good if it passes those. Any fakes I have heard of are very obvious. Gold coins are hard to fake. The only thing that scares me are gold bars that could have a tungsten center. Fire assay is the only sure way to know in that case.

@ptaeiy Calipers don't do anything for un-graded, un-slabbed coins. If you get a Buffalo that was struck too hard or has some finning, then so much for the caliper test.

Some fakes can be the same weight as a real if they use a mix of metals that works. Thats why there are so many test. Including diameter and thickness to measurements to compare to real.

Glad it was helpful!

De nada, me hermano!

Good, more for the smart people

and the last test I like to do, if you're still not sure. You can go to your local Home Depot and get a table saw.

My thought exactly. However, I think that that specific gravity machine is especially useful in case you're dealing with golf object with a more random shape. An example of such an object would be a gold bar.

@@goldaddict6427 hence the reason to avoid gold bars and stick to 24k govt issued non-numismatic coins of standard dimensions?

@@mth469 Yes, unless you regularly buy gold of different shapes and sizes. In that case, you're probably running a business in which you regularly deal with gold objects.

@ptaeiy I would have thought the wavelength of Ultrasonics was too long to accurately measure down to sub-millimeter accuracy. Have you found any fakes with your testing methods ?

@ptaeiy Best to stick with 24k as it makes detecting fakes easier.

Yes, but it will have its own sound!
