Seems pretty plausible that those fat bars could have a relatively fat tungsten core with a relatively thin gold plate or clad, with consequent high profit margin.

Seems less plausible for coins firstly because you would need a relatively thick clad of gold over the core in which to pick up the fine imprints of the coin stamp - - tungsten is very hard and would play hell with the presses, I think. Secondly, the percentage gold then required to make a fake would really increase over that of a bar. Thirdly, it brings into question the mints who make the coins.

So, bars: maybe so, of no concern to my small appetite for yellow burials. -g-

Several good posts today about NDT (non-destructive tests): electrical conductivity, thermal conductivity, xray density. They'll catch 'em if it's true.

JMHO

I do specific gravity test on all physical gold.

Weight, volume.

Tungsten may be close, but it is not gold.
