I remember that story, it was the IMF selling 400 tonnes of it and they had 200 left  and Sprott offered to buy it. Wow, that was well over 2 yrs ago, feels like last yr to me for some reason.. The most hilarious reason IMF gave was they didn't want to dump 200 all at once and disrupt markets, meanwhile they already had dumped 200, were disrupting markets ever since they announced it PUBLICLY, and were planning to dump the rest anyway ..
