I presume you guys have all heard about the Tungsten/Gold Bars scam?
Be careful what you invest in.
ONQ.
It is a theory/rumor at the moment. I have spent a couple of weeks searching news articles in the US, Canada, Australia, UK, Ireland and Germany. Not one of the dozens of articles was able to point to verifiable facts about gold plated tungsten bars. A lot of the articles have an early stage "conspiracy theory tone" to them, with statements like "a trustworthy source of the writer has verified that there are huge ongoing investigations on gold reserves in XYZ" and "verifying authenticity of gold is very difficult and time consuming as the bars have to be drilled individually" (all with lack of references).
I'm not saying that it is not true. What I am saying is that I have yet to be shown proof from some sort of commodity auditing company. Bottom line is that buying anything involves a certain amount of trust in the person or company you buy from; when you buy food you trust it won't poison you; when you buy a car you trust it is safe and in sound working order; if you buy shares you trust the broker actually bought the shares and didn't do something else with your money. Buying gold is no different than anything else.
