Restricted trade ended around the 14th January 2011. Before that there was clearly a large discrepancy involving the Grand Exchange value and street value for Rs 3 Gold. When you could only offer +-5% no-one would sell any Partyhat for a huge selection of mills less compared to the street value.

This huge disparity meant rares wasn't traded on Fantastic Exchange which meant the Grand Exchange value doesn't update (or perhaps updates very slowly and gradually). The massive peaks from the beginning of 2011 have been ppl putting their Partyhats around the Grand Exchange for actual price and also Grand Exchange changing correctly. From 2007 : 2010 most Partyhats were inside the 300m-1b range, we were holding not under 100m rs rare metal.
