This came across my desk http://goldenfront.ru/articles/view/gold-bugs-beware-fake-mex-gold-peso-coins-come-moscow Lesson for me on this is the necessity of basic checks to spot the fake, same as those China PM bars on Channel 7, which were cheap copper rip offs that would not have been anywhere near the correct weight.
Such a nice coin too. Thanks for posting, it's nice to keep up to date with what the frauds are doing.
