The Neodymium Rare Earth Magnet For Spotting The "Fakes"

Well i just got mine in today ! N52 grade neodymium rare-earth magnet.

To tell you the truth i really didnt see the need to buy one of these as all
Of my bullion purchase were going through reputable sources like APMEX
J.M Bullion, and my local dealer who tests everything before buying it
So have felt really comfortable with my purchases, however my focus has
Since changed, i,am now primarily investing/ collecting Johnson Matthey
10 OZ Silver bars, and many can only be found on the bay, and you have
To be very careful there as allot stuff is silver or gold platted and being sold
as real, so how do you find the fakes or scammers ?

You first start with a magnet like this one i have pictured and you can get this
American made product for about $10 including shipping, have already tried
it out and this little think is powerful !! if there is something metallic in your
Bar or coin this thing will find it.

Once you have gotten through that step, you should be filling pretty confident
That you have the a genuine article atleast from a metals point of you, but
some people will give you bullion but try and copy the brand, so detailed pics
are very important and many websites will offer examples of so called "Fakes"
and can tell you what to look for.

Moving on the next step is weight, if your still on the fence on weather or not
You have an authentic item just weigh it, many coins, bars and other bullion
Items have exact weights if it,s under or over you may have an issue !

Bottom line, before you go out and spend your hard earned money, educate
Yourself on what your buying, and have the proper tools and knowledge to
Make the right decisions.

Great idea! Where did you buy it?

 

Very good advice. You can also get the neodymium rare-earth magnet from an old computer hard drive. I like the pic you posted that looks like you can put it on a key chain. May not be the best idea? After looking at it again, maybe the link is for hanging on a non metallic hook..

 

So, it is good to test wooden nickels?

Actually a good idea, we know what you mean.

 

Well done.
Next step a Metric digital caliper

I have a larger Neodymium Magnet. (1/2" x 1" x 2")
Has a lot of pull (have to be careful where you set it down) it will get you in trouble Quick.
I keep it in a little wooden box and stick it on the cabinet.
(the wooden box makes it so I can remove it easier from the metal cabinet and isolates it from potential hazards)

It's not really practical to carry around to coin meetings or shows, It sticks that good.
The last coin meeting I borrowed a magnet for another member and it probably saved me a $100 detecting some fake Libertads.
my new magnet showed up in the mail today.

$6.99 on the Bay, Will pay for itself First Time Out.

Here,s the ebay link where i got mine, cheap insurance to protect you from
The scammer !

 

To add to the above, shipping is really quick with this guy ! ordered it on Thursday
Night was here in the mail Saturday morning waiting for me

 

It is not at all clear to me from your write up as to what this does and why it is different from a regular magnet. Could you please explain.

 

Is it safe (for the phone) to carry these things if they are close to your smart phone?

 

What if you get a fake magnet??? ...

 

The difference between a regular magnet and a Neodymium one is power
And strength, the one i purchased can fit on a key chain, and can lift a large
Hammer with ease here,s a link to a video showing there power.

Here,s a video for you that proves that addresses your concern

Then you return it to mother earth, dont know why she,s giving you a fake..LOL

 

You should be able to pick one up at any dollar store or surplus outlet for a bunch less than you guys are paying for them. Common things for mechanic's pick-up tools. Neodym magnets are also used to drive the speakers in earbuds and small headphones, if you happen to have a pair that got ruined somehow...

 

I still don't understand. How will this detect a tungsten core? I don't think tungsten is magnetic, otherwise it would be easy to detect as a replacement for gold.

 

It will not detect a tungsten core as that is non magnetic, one way to detect that
is by weight.

 

Tungsten is 99.75% the weight of gold. That is a difference of much less than a tenth of a gram for a one ounce gold bar. Most people are not going to be able to detect that.

 

Tungsten/gold engineered bars can be detected by use of ultrasonic flaw detectors as acoustic patterns are quite different. These instruments are used more for large metal castings but have been adapted to gold bar testing and commercial spinoffs of a less ability by sellers on eBay and bullion sites. This site can give more info.

I can sell you a piece of iron to test that...$25 and free shipping (DISCLAIMER...NOT A REAL OFFER)

 

Thanks, Rusty, I'll buy one to use when I'm looking for silver items.
