Hi, love the vid, I would recommend you update your Sigma to database no 1.35, I have just done mine as it will have a wider selection. Have you done the specific gravity test on the sigma.
1965. Oh I bought my Sigma Pro many years ago from Sigma in America. I’ve never updated it as thought it would have to go back to the US. Please send me the link.
@ I’ve have a fake ancient gold coin that is 24ct. They couldn’t refine to that level back then. Also a perfect size and weight twentieth of an ounce Libertad that was gold plated tungsten. Lots of re strike sovereigns & half Sovereigns from 18-23ct.
If anything this video has discouraged me from spending a small fortune on a machine that can’t tell the difference between the fakes and the exceptions to the rule. It’s a lot of money to spend only to still not be entirely sure if it’s genuine or not. I thought about buying one a while back, but to be honest I buy the vast majority of my silver and gold brand new from reputable mints, and jewellery from reputable jewellers. The only exceptions are the old coins and trinkets that I’ve picked up at the local flea market but it’s not enough to justify paying that much for the coin tester. For the price of that machine I might as well use the money to buy new coins that I know for certain are 999 or 9999 fine. If it’s your business to be buying 3rd party coins 1965 or otherwise then it’s probably worth it’s weight in gold and not something you can afford to pass up on. Great video though buddy, keep it up ✌🏼❤️🪙
@ of course, it’s better to know if it’s not entirely perfect, even if it does turn out to be an exception to the rule. If they do change the metal content and weight of future sovereigns, will they be able to update the machines accordingly or will that require a new machine?
@@BackyardBullionwouldnt the size be accurate looking up their thickness and width including weight ..its not easy to fake the size and have the weight be correct..plus the magnet to add on.
Hey all, i usually test my metals with scales and earth magnets. i came across another way to test your silver it takes seconds i was doing about 25 coins all at once,you take a plain white sheet of kitchen paper lay down your silver coins/bars and place the sheet on top all real silver will illuminate a white glow underneath any fakes wont, as the sheet is fairly thin you will still be able to make out the shape of the fakes but thats to be expected,just wanted to pass this on if anyone wanted to give it ago i did on all my silver and it worked great on all cost wise that sheet of paper cost about one cent 😂 you can use plain toilet paper aswell but the sheets are smaller , love the channel happy stacking. 1965
My sigma has paid for itself 50 fold in some of the bad things it has found ... even from reputable dealers ... full disclosure ALL were very fast at correcting the issue and i check EVERY piece that comes through my door , even if its 10 tubes
65 was a good year... my first - lol. Good to see the SG test - I only knew about the tests we did at school, with a weird beaker with a pipe on the side, and overflowing water to be captured and weighed... always thought this was way too clunky to be any use. Think I'll talk to some buddies about sharing a sigma... I know of a freelance surveyor who has a xrf machine for his work, and for a small fee will test precious metals - worth asking around if anyone wants certainty. **edit** ps. the blurb says that the sigma machine can do SG itself - is there a reason you don't use this?
I can’t wrap my head around this. If the weight of the coin is suspended from the string, then how does it impart any of it’s weight to the water? And does the shape or dimensions of the container (which would change the dimensions of the column of water being used) make a difference?
Precisely, why go to such merry-go around to purchase British Gold Sovereign ... purchase the Britannia 999.9 purity. If not mistaken Britannia Gold Coins still have exempted VAT and CGT advantages because they are classified as legal tender.
1965 & all that. I brought an 1887 quintuple sovereign from The US last year. {Ironically I managed to obtain a very good replacement from a coin shop in Sydney, one I worked at over 40 years ago.} Turned out to be one of those infamous 1960's Lebanese jobs. Since I started coin collecting circa. 1968 it was only the fourth time I've been knowingly swindled on a high end coin. Although the coin was fake, it had more gold content than Royal Mint issue. I wonder if there are any of those skilled counterfeiters still around over in The Middle East today, as I'd like to see them employed at Llantrisant. At least we might get some fair prices if there is a little extra gold in their products. 😏
@@BackyardBullion Thanks Backyard, you're Sigma is pretty amazing as well. Your videos are always interesting, like a good book I always read you to the end. 🙂
In a sense they're not even fakes, just a way for people to trade in the Middle East in gold using something respectable....In a sense faking a 5 sovereign gold coin was their idea of a mintmark... There's still loads of fake sovereigns for sale...they're still real gold....but they're pretty easy to spot these days and they sell in Dubai gold souk solely at spot price....Real sovereigns are a bit more expensive.
Just bought my first gold Britannia today and a couple silvers from you. Say I sell it in 10yrs time how much would the person I’m selling it to take commission? From my research it says 2%. What would you say as you have miles more experience with bullion than myself many thanks in advance
Surely this only proves that the Sigma machine does not have this coin in it's own database, therefore it doesn't recognise it, due to the different alloy content? This maybe why Sigma wish to have the coin in their lab, test it, confirm it, and it to their database. 1965 is a while ago now.
If I buy gold here in Switzerland then it's only 999.9 (24 carat) quality and for bars with LBMA certification, all from reputable dealers. I'd rather pay a little more for the peace of mind. Same applies to my silver.
That is an inappropriate way to use the sigma. You test against what it should be, not against other alloys that it might be. They are programmed against specific alloys, not the other way around.
@@BackyardBullion yes but because this coin isnt on it, is it not worth seeing if it passes as a 24k brit or 22k eagle just to see, cos going by your gravity test it could be 23 to 24k and thats why it fails a sov test
Instead of sending it to America, Chards has a Nitron machine and will list all the metals by percentage. Secondly why didn’t use the Sigma’s own “pacific gravity” setting, press ‘measure’ and follow the prompts.
I can’t wrap my head around this. If the weight of the coin is suspended from the string, then how does it impart any of it’s weight to the water? And does the shape or dimensions of the container (which would change the dimensions of the column of water being used) make a difference?
It's because it is measuring the difference in weight of the volume of water displaced by the gold. This then weighs more of course, because gold atoms weigh more.

I will find it at some point, your best bet is to email trustimetrix and they can help
You don't need a sigma to know if a gold coin is real or fake, You need a sharp eye, I call it the golden eye

I would disagree 100% without this machine I would not have been able to know there is something off about these coins.

I said in this video near the end that you can update the machine remotely.
Buy a FAKE 1 oz Gold buffalo 🦬 for almost $3,000.00 and you will WISH you had the pro machine!!

That's not a definitive test, but a helpful one to do a cursory check
@BackyardBullion have you tried it yet on some of your silver I'd say you have 👊

Have you tested it with the Bullion Wand ?
Great vid any discounts on the sigma ?
👍🏻👍🏻👍🏻👍🏻would like one but way mega expensive sadly😢
These are expensive for a reason. They are exceptionally good pieces of technology.
What about a ping test? I have had similar results from my Sigma. Had sovereign which failed sigma and ping but turned out to be jewellers copy.
I’ve just seen Cobrastackers gold Queen’s Beasts!!! If you get someone selling the same set in 1/4 oz gold I would love to buy
They are amazing!
I havent gone with specific gravity test in a while. Knew the moment I saw the floss
Lovely 1965 Sov!

Sir, pay attention to Fake coins made by Tungesten alloy, as it has same density as gold. So i think SM IS accurate !
Loved that, super interesting.
1965 amd Great Video! alway very interesting and informative for a newbe like myself! thankyou!
Glad you enjoyed it!

Yep, this sounds about right to me!
They 3rd party sovereigns aren't sovereigns in my eyes a sovereign comes from a branch mint or the royal mint
Surely this only proves that the Sigma machine does not have this coin in it's own database, therefore it doesn't recognise it, due to the different alloy content?

sure it aint 24k and that caused the fail, why didnt you just do more tests til it passed on one

I could have done, yes you are right.
Very interesting!
Glad you think so!
has anybody else got the kitchen scales out after watching this or is it just me?
1965 great watch thanks bybullion
My pleasure!
great video. thanks
Go to someone that has a XRF MACHINE TO TEST IT .
Err what about buying from the reputable dealers then? Baird, chards etc etc.
Yeah, 100% this is a great way to stay safe.
@@BackyardBullion Even reputable dealers happen to buy non-genuine sovereigns from time to time, but still...
Why don't you try different gold settings for those questionable coins?
That's not how the machine works. This could lead to false positives or negatives. You should only test against what the coin is supposed to be.
@@BackyardBullion Say the coin was of a higher purity, then the machine would catch that. Or vv. Just try it for fun.
I worry about Triston de cuna gold coins
Yes, they are garbage and you shouldn't pay more than 90% of spot price on them really.
Sound quality going high and low !
Sorry, it's a big echoy room
It's interesting stuff? Just hard to concentrate at times. Thanks 😊 1965
Any particular timestamps? I listened to the video and it all seemed fine with me on my phone.
@BackyardBullion apologies, my phone is now doing it with another video..sigh... your video is probably absolutely fine !
1965 was a good year ✨️
Way before my time sadly!
Great video. 1965..
1965
1965. 😂
I just wouldn't touch those coins again tbh
Nope, me neither.
FFS I hope they're not
I think they have gold content but I wouldn't buy them
