One Tonne Gold Coin
 

With the recent ton vs tonne debate, here it is: the ultimate gold
coin. 1000Kg of 99.99% pure gold.

http://www.liveleak.com/view?i=923_1322908267

1000Kg = 2200 lbs.
2200 lbs. x 16 oz./lb. = 35,200 oz.
Gold is currently $1745 US per oz.
Coin is worth $61,424,000 US

I am sure, since this coin is so large, it is for all practical uses
valueless. So if you Aussie guys are looking to get rid of this
albatross, you may feel free to drop ship it to my house.

It is interesting to note how small it is, for one ton of weight. Gold
is so dense.

Its no more valueless than a large safe filled with $100
bills...well..humm...ah...err....eeep...lets change that to a large safe
filled with $61,424,000 worth of diamonds

Its just gonna be really hard to get change if you buy something.

And the value seems to be rising at a significant rate..unlike
diamonds....

Yeah, OK, but (obligatory metalworking content) it's just a disk
unless it was shaped by die pressure (coined). So, it's not
really a coin, unless one of those stamp-out-tank-turret
bits of heavy machinery was employed to shape it, against
a carefully sculpted reverse-carved die.

If the rest of the English speaking world cuts Oz some slack, speaking
Strine will allow you to keep your probationary status as a member of
the English speaking countries. Too many additional funny words for

I suspect Carbide like the carbide vessels sold to melt metal in.
Graphite might burn off - oxidize and loose 'face' ! :-)

The fact that it is on the graphite supplies.com site might tell.
But gold is a hot metal 1064 to melt I don't know combustion - likely
much higher. Maybe I'm worrying over nothing.

I know when doing metal molds one always 'smokes' the faces - put carbon
on it - as a release material. Otherwise the metal might try to flux
and amalgamate with the mold.

So it might be steel or bronze coated with a good layer of carbon black.

Yep. Tinnie is also used for a beer. True Aussies prefer the beerincans as
its easier to cool down quickly. If you have access to a buld propane truck
a couple of squirts of liquid propane will cool a tinnie, but it will break
a bottle.

Why bother with converting from metric units?
The current price of gold here in UK is £35.835/gm. 1000Kg is
,1000,000gms, so the amount of gold is worth £35,835,000. At the current
exchange rate (today is 4 Dec 2011) that is $55,884,681.77

That's a really interesting question, but the answer isn't that clear.
"Coin" derives from a word for "wedge," and some sources say that the
earliest stamping dies were wedge-shaped. This is a misreading; the
fact is, the earliest coins were shaped like a bronze ax-head, which
is where the "wedge" comes in.

The next step was flat coins with a stamped image of an ax-head struck
into them. So striking, or stamping, became an accepted part of what a
"coin" was.

Today, we have fully integrated the idea of stamping or striking into
our definition of "coin" (the verb), but it is not a necessary part of
"coin" (the noun).

Still, I think that most people would agree with you that this "coin"
is not "coined," so it's not a "coin." Bullion (from "boiling")
generally is just simple cast blocks or sticks, sometimes with a
weight and/or a certifying stamp struck into it. So much of the
bullion in the world is coined. d8-)

into them. So striking, or stamping, became an accepted part of what a
"coin" was.

Today, we have fully integrated the idea of stamping or striking into
our definition of "coin" (the verb), but it is not a necessary part of
"coin" (the noun).

Still, I think that most people would agree with you that this "coin" is
not "coined," so it's not a "coin." Bullion (from "boiling") generally
is just simple cast blocks or sticks, sometimes with a weight and/or a
certifying stamp struck into it. So much of the bullion in the world is
coined. d8-)

The video (as at http://1tonnegoldcoin.com/) appears to show handwork
stippling, ie stamping small marks into the surface. See particularly
http://1tonnegoldcoin.com/img/gallery/full/18.jpeg and

Re pressure in mold, it would have been ca. 22 psi near most of the
bottom edge of the mold (~ 31.5" diameter * 0.698 pounds/cubic inch)
and ~ 28 psi in the bottom tab extension of the casting.

That's actually a lot. What's the total force trying to push the mold
halves apart? About (22/2)(Pi (31.2/2)^2)= 8,572 pounds, with max force
at bottom and zero force at the top of the sprue.

If the rest of the English speaking world cuts Oz some slack, speaking
Strine will allow you to keep your probationary status as a member of
the English speaking countries. Too many additional funny words for
things, and your probation will be revoked. :)

BTW, I thought a "tinnie" was Strine for a can of beer. I would be
lost in Oz without some quick lessons in the local dialect.

Yep. Tinnie is also used for a beer. True Aussies prefer the beerincans as
its easier to cool down quickly. If you have access to a buld propane truck
a couple of squirts of liquid propane will cool a tinnie, but it will break
a bottle.

Why does that strike me as quintessentially Australian?

Like the jet powered beer cooler? (Hmm ... Kiwi, not OZ, but
not that different from this remove. (GD&R) :-)

It's marginally safer to use a truck with bulk Carbon Dioxide or
Liquid Nitrogen, but Propane works fine if done with a bit of care

Liquid Oxygen would work too, but any loose oil or grease and it could
also get real exciting, real fast. Heck, you can light asphalt paving
on fire... Let's not, and say we did.
