Hi Scruffy, it seems the jury is still out on whether the suspect bars are indeed part of a systemic fraud that is several years old or a recent plant by the bullion banks to scare new investors away from purchasing physical bullion. If it is a newly formulated idea then it just might backfire on them, similar to the impact that IMF gold sales has had on the gold market. Either way though, I am sure the assayers will be quite busy for an extended period.
