Telling the difference between a gold bar, and a gold plated tungsten bar is quite easy using several different methods using current technology, without using deformation.
Paramagnetism:
Using the gold bar inside a coil of wire with a constant number of turns, at a constant voltage change (AC) it should be possible to tell the specific paramagnetic properties of the metal itself by the following formula:
L = a4(pi)N^2µA / l
Where:
L = inductance in Henry's
A = cross section Area
µ = Magnetic permeability
a = constant
l = length of coil
That way, two different metals of the same dimensions would register with different magnetic properties.
A simple resonance circuit could be set up with the "Gold" being the inductor for the circuit, and a capacitor with a known capacitance.
Therefore, the circuit would only work on GOLD of those dimensions as long as it is SOLID gold, and not if it is tungsten.
Another method would be radio frequency transparency / reflectivity... and could be accomplished using a simple radio circuit.
Another test one could use would be testing the circuit resistance of the gold bar using a mega ohm meter (high voltage ohm meter), since the electrical properties of the gold in a tungsten core bar could only appear to be different if the core current surpasses the surface conductivity.
Another test would be an ultrasonic probe, that detects the acoustic properties of the bar (as tungsten rings at double the frequency of gold)
These gold bars should each be submitted to a battery of electromagnetic, sonic, and radiotelemetry analysis before they are even accepted AS gold.
Im sure the testing "Kits" that I described would cost less than $1'000 dollars for all three methods.
But a simple inductance test you could manufacture for less than $10 using a coil of wire and a power source.

Roughly 15 years ago – during the Clinton Administration [think Robert Rubin, Sir Alan Greenspan and Lawrence Summers] – between 1.3 and 1.5 million 400 oz tungsten blanks were allegedly manufactured by a very high-end, sophisticated refiner in the USA [more than 16 Thousand metric tonnes]. Subsequently, 640,000 of these tungsten blanks received their gold plating and WERE shipped to Ft. Knox and remain there to this day. I know folks who have copies of the original shipping docs with dates and exact weights of “tungsten” bars shipped to Ft. Knox.
The balance of this 1.3 million – 1.5 million 400 oz tungsten cache was also plated and then allegedly “sold” into the international market.
Apparently, the global market is literally “stuffed full of 400 oz salted bars”.

Most currencies aren't based on the gold standard, they are a fiat system which means they are based on the speculation of GDP.
