Post your copper Bullion

Since i just started a small collection of Copper bullion, i think i cant be the only one on this forum to buy it
There are the 2 i won in an auction, still need to get them delivered, but they are mine anyway
So let me see your copper bullion's

I flattened the relief off 3 pre-'82 pennies and polished them to a mirror finish last weekend to make a new heat sink for my laptop. Made the laptop run at least 20C cooler. Does this count as bullion?

 

Can you post a picture

 

Copper bullion is a fad, scam and sold by snake oil salesmen. Sadly, there are people out there who will buy anything that anyone calls bullion. Melt it down into a coin form and someone will buy it for way more than it's worth. They might call it a "premium" but don't be fooled, it's call their profit. Next thing you will see people sending these off to NGC and PCGS for MS70 slabbed copper. Really?

Remember that a fool and his money is soon parted and there is a sucker born ever minute.

 

No because they are in use now. I can post how you can use copper pennies to make your laptop run cooler if you have overheating issues. However it would be extremely OT.

 

Koen,

I don't collect copper bullion as such, but I do have quite a few medals that were struck in copper. I bought them for the designs rather than the metal content.

well, i buy it for the designs to.
But this fool (as andrew thinks i am, but no offence taken ) is not paying verry much for those bar's
Now i do no know how it is in the US, but here in Belgium copper thefts are booming business...
But as said, i also buy them for the designs, not for what material they are made of.
I can buy silver or even gold bars with the same design, but the copper ones are more to my budget at this moment

 

:yes:

 

copper is even better than silver (oke that is a lie )

 

Too bad copper low metal desnity means you can easily fool anyone with alloy of almost any metal out there. Hope you can tell difference between copper plated zinc/lead bars and copper bar.

 

Koen,

I'm waiting for them to start making aluminum bullion before I get in to the market. Until then, I'm hoarding rolls of aluminum foil.

I hope to be moving to Brussels in July ..whats the coin shop/where else can you buy bullion ..over there?

 

I don't know about the rest of the country, but CPVC has pretty much taken over the home construction industry in South Florida, and copper pipe for water supply is a thing of the past. Thefts of copper pipe from construction sites used to be so bad that deliveries would be delayed until the plumbing crew was onsite and ready to install it.

Running an electric current through it will quickly let you know if you have copper or something else.

 

That will still work if it copper plated or it is made off Aluminum

 

Not if the current is high enough. The differences in the resistance will quickly show up. Of course if you had a bar of aluminium vs one of pure copper, the weight difference is pretty significant.

 

Hmm won't current travel via the plating not through the core of the metal? Path of least resistance. I am referring to an aluminum alloy.

 

to test it it is not that hard.I have a table with dencities of almost all metals (and all the common ones are on it)
Altough some of them are close togethere, none of them are the same.
So it is not that hard to find out if it is real or not.
With a small test you know the results of it in a few minutes

 

That is where the problem is the amount of alloys you can use to match the weight of a specific copper object is considerably more than silver and we all seen how may fake silver coins/bars are coming out of china that match specs exactly nowadays.

 

Exactly. Since there is a small amount of copper, atoms thick, the plating will go "poof". If it was that easy, they would simply use copper plated steel instead of copper wiring.

But there is another problem.

Copper in the presence of aluminum will experience galvanic corrosion so I would expect this is something you would not want. It can done, but I don't think it will last. This is why so many houses burned down in the 70s when aluminium wiring was used to save money. The outlets, light switches, fuse boxes, etc all still used copper, galvanic corrosion set in, resistance went way up causing heat when the current was on, new business for fire department.

 

lol this is a joke right?
