Bring it to a pawn shop they will test it and give you a price.
Decline the price and walk away.
You got your coin tested for free.

Tungsten residue is normal.

>>15717791
yeh but what if they try grinding the coin?

>>15717942
the only way to be 100% sure it's real is specific speed of sound tests. that's non invasive for the most part. anything else is bullshit that can be easily spoofed.

>>15717981
Except like measuring the volume and measuring the mass and seeing if the density is exactly that of gold

>>15718007
>>15717981
do you guys see the part of the coin that I am questioning though?

>>15718007
>Except like measuring the volume and measuring the mass and seeing if the density is exactly that of gold
easily spoofed
when i said specific speed of sound is the only non invasive method that is 100% sure i meant it. tungsten and osmium for example both go for fraction of golds price in the right ratio gives you golds specific weight.

>>15718084
we do, anon

>>15718139
I just feel like it's too beautiful to be a fake

>>15718084
clean it with sulfuric acid, if it's just dirt or other contamination the acid will remove it.

>>15718165
where can I get that

>>15717774
Do not listen to the idiot that says to clean the coin. Leave it alone. There is nothing wrong with it. You bought an old world coin I'm guessing AU condition there is nothing wrong with it. If you wanted a pristine BU coin you should of bought a 2019.

>>15717942
OMG you must be the poorest fag on this board.

>>15717774
fake af

>>15718230
nowhere if you are in london
otherwise chemical shops maybe electronics suppliers it's used for printing circuit boards and cleaning and stuff

>>15718265
There is nothing poor if he want to keep his coins nice looking dumb shit

Nice. Ruby sapphire opal... What is the white thing?

>>15718340
Highland Park?

>>15718424
a complimentary opal that came with the nicer opal
The ruby is untreated and is a blood ruby and the only treatment the sapphire got was heat.

>>15718230
Heat down battery acid from an auto sply place carefully to get pure. Or extract from battery and separate from lead sulfate by freezing the liquud. To get some semblance of purity

Some drain cleaners are also sulfuric. Look up the sds online by product.

>>15718299
>nowhere if you are in london
i shouldnt have laughed so hard

>>15718265
A refinery will likely melt it down regardless if he sold it to one

>>15718543
kek

>>15717774
nice looking Austrian ducat

you could invest in a jewellery scale and a finely graduated volumetric flask and calculate the density yourself.

Nevermind guys...

my wife cleaned it with a Q tip and it's all better now

WHEN I TRIED CLEANING IT, even though it is very very tiny, I SCRATCHED IT. Is it fucked?

>>15718713
No, unless you were trying to collect for collectors value or whatever, what are you 12? Are you sure your mama didn't clean that coin?

>>15718713

>>15718765
naa im just collecting gold for weight.

And yeah I wish I was 12. Fucking up at 26 like this is patheric. I'll take every insult right now because honestly I need a punch in the face. Gold is one of the softest metals and here I go like a dumb ass.
Seriously I'm retarded.

>>15718788
You can still fix it, just get a blow torch and carefully melt that section, should come up looking good as new.

>>15718230
Muriatic acid from the hardware store should do the trick. Converts to sulfuric in the presence of water iirc

>>15718237
>t. Apmex

>>15718853
kek...eghh thanks anon but I fuck up shit easy.

and now its worth only scrap, dumbass.

>>15718788
Don't listen to this retard >>15718853
Just get more of them, I've done similar things, one time i got so bored with my fractional gold i took it all and pounded it into a small ball with a hammer and a cheap chinese vice press with a flat surface. Gold is gold, so unless you have some super rare BU coin or something (which you should have in a case anyway) then it doesn't matter.

>>15718713
It seems you bought a chocolate coin. Well done.

>>15718713
Yes it’s fucked. Just knocked off at least $500 by doing that. Way to go idiot.

Try and crack it open? Is it filled with chocolate? Looks like Jew gold to me OP.

>>15717774
Boomer rocks, the thread

>>15718121
got any evidence of fake coins being made out of 2 different metals? Never heard of this, even in bars

>>15719041
that's exactly what I told myself
"fuck it, I learned of my mistakes and I'll get a ton more gold and forget of this mistake".

>>15717942
No dealer grinds a fucking coin. They'll use an electronic device which the name escapes me but they're expensive and really accurate so if you move a lot of metals you'll have one.

>>15717774
have fun with your boomer rocks.

>>15719586
they are beautiful and I cherish this collection as it will grow. Enjoy your stocks.

>>15718397
Succubus from Pheli in the bottom center?

>>15719412

>>15719814
close, it's just a standard angel coin from Amy's collection. It was overpriced but I got it because it's beautiful.

>>15718973
Muriatic acid is HCl not H2SO4

>>15719826
pamp suisse rippin everybody off

>>15719826
thats 1 metal, try again

>>15719586
have fun losing 20% every time the miner pool farts, you fucking nigger animal

>>15719962
kek I hate the packs they come in.

>>15719962
Only if you're stupid enough to buy from ebay.

>>15718165
DO NOOOOT DO THIS OP! THIS WILL MELT YOUR GOLD!

>>15720532
yeh I figured.

nice gold anon
don't worry about a scratch, I have a lucky gold coin I flip when I'm bored and it's all dinged up
but those pure gold coins are soft, krugerrands are 10% copper 90% gold and are a stronger alloy

try biting the coin to see if it's pure

>>15720571
That's why I'm becoming a fan of pre 1933 gold from the usa. They are pretty beautiful.

>>15720568
Do you hold any LINK OP?

>>15720568
Lol,oh shit, would it really? I thought I was just trolling. Gold seems too strong and unmeltable without a crazy blowtorch, but Im no scientist
>>15720598
>Gold is a soft metal, and thus conventional wisdom says that the deeper the imprint your teeth make (without revealing a different metal beneath the gold), the purer it is. However, this test would not be foolproof: Gold coins can have a core of lead (for the weight) which is soft enough to leave bite marks in. In fact, historically, gold was typically alloyed with other, harder metals to make it harder, while still maintaining the standard gold weight. Thus, the bite test was actually a means of detecting a lead forgery (teeth marks) versus a real minted gold alloy coin (no marks). Also, gold is an excellent heat sink; most metals quickly heat up when they're held, but gold remains cold in one's hand for some time - and the lips, tongue and teeth are even better than fingertips at detecting changes in temperature. Alloyed or cored gold heats up faster, and biting it is an easy way to test this - though in more polite settings, merchants kept a bottle of acid by the cash register; gold is a noble metal which is resistant to change by corrosion, oxidation or acid, so a merchant could determine the purity of gold by putting a drop of acid on it AKA the "Acid Test."
Huh, well TIL

>>15720639
no.

Want to pull the trigger on 20 Silver eagles from Ampex. Something to throw in the safe with my pistol/cash/id
Why shouldn't I do it?

>>15717774
Take the coin and flip it in the air if it isnt the most beautiful sound you have heard its fake.

>>15721080
A monster box belongs next to a gun in a safe 1 roll or 2 of eagles should just be laying around the house.

>>15720764
Well if you want to buy a lot of gold in the future then you should be holding at least a suicide stack.

>>15719826
That's a chocolate bar, you can buy those. ..they are pretty good

>>15721080
I pulled the trigger when it was at 17.50 earlier this week. Remember if it's under $20 an oz we haven't even launched yet. It's not late to accumulate.

>>15719134
I'll pay $300 under spot but that's the best I can do.

hello greta

Go to youtube and search for water weight testing gold coins. First you have to fill a clear cup with water and then put it on the scale and reset it to your new zero kg/lb with the cup of water on it.
Then you make a little rope around your coin and build 2 pillars standing around that cup of water on the scale.
Scrap the end of the rope to the middle stick which is hold by the 2 pillars and dig your coin in the water and notice the water rejection of the coin by looking at the new mass of the kg/lb display.
Sorry for my bad english anon but if you didnt understand me you'll better watch youtube videos doing the exact same example.

I did it for me and my coin turned out be real (no wonder i bought it from a well known german-jew chain jgold seller degussa)

>>15721217

Sure thing bro.
Lets just buy some crypto shit which is used by nobody not even normies are understanding cryptos,
I'd rather prefer stocks which produce goods that normies buy instead of buying hot air coins which are backed by nothing

>>15719412
dunno if its been done on a large scale but its easily doable inexpensive if you are already doing inserts tungsten + a little of some heavier than gold metal will make these stupid water tests pointless.

>>15722235
idiot
get your coins checked with ultrasound

>>15721192
it doesn't ring like a gold eagle
