The highest value usage for this technique may be separating bullion gold from gold-plated tungsten.

Not all who wander are lost.

Is gold plated tungsten very common?
I'd imagine it would have to be a thick layer of gold, right?

Fake bullion is a problem...how big or small a problem nobody knows yet.

That's not a dollar, mate...THIS is a dollar.

Has anyone ever ran into any?
I guess it would be hard to test, but it seems like the expansion of tungsten vs gold would differ at some point, causing the difference to be great enough to measure by figuring out its volume via water displacement.

this is from DollarDaze.org

A Chinese company called Chinatungsten is advertising imitation gold merchandise on its website. The following quote is taken directly from their Tungsten Alloy for Gold Substitution page:

"a coin with a tungsten center and gold all around it could not be detected as counterfeit by density measurement alone ... We are well accustomed to exploit more innovative applications of tungsten products. Gold-plated tungsten is one of our main products."

Hoard now and hold on!

Got my ACE from Santa, I have not been able to put it down, what a great device went through 2 bags of pennies, took me a week before. I count a bag finished when zinc is rolled and ready to be dumped.
