Here's a head scratcher: as everyone knows from elementary chemistry courses, gold is the most inert metal in the world - it does not rust, nor corrode. Yet this is precisely what Russian commercial precious metal trading company, International Reserve Payment System, discovered on thousands of (allegedly) 999 gold coins "St George" (pictured insert) issued by the Central Russian Bank. The serendipitous discovery occurred after various clients of the company had requested that their gold be stored not in a safe, but in a far more secure place: "buried under an oak tree." As the website of IRPS president German Sterligoff notes: once buried, "the coins began to oxidize under the influence of moisture." And hence the headscratcher: nowhere in history (that we know of) does 999, and even 925 gold, oxidize, rust, stain, spot or form patinas, under any conditions. Furthermore, as IRPS discovered, Sberbank of Russia released an internal memorandum ordering the purchase of the defective coins with the spotted appearance. Sterligoff concludes: "It should be noted that the weight and density of the rusty coins coincide with the characteristics of gold that would be expected after after conventional testing methods would reveal. We think that the experts will be interesting to determine the nature of this phenomenon." So just how "real" is 999 gold after all, either in Russia or anywhere else?
