I think that a lot of this has to do with a new growing category. Everyone rushed to sell their coins there. I wonder what the chart would look like if there were only 5-10 coins for auction. Many of these coins have low mintage and as category grows in popularity and coins get harder to find the premiums will continue to grow. Its guaranteed as time goes on these coins get more evenly dispersed. Right now were still at a point where 250 people hold 70% of the coins (just a guess). Physical bitcoin will grow and go through the roof, ITS SCIENCE
