agreed that it's off the topic as it's a panda forum
however, it's somehow relevant to all MCC investor/collector to understand the reason behind massive price discrepancy evidenced in auctions. image someone who is unfamiliar about this paid top dollars for some common coins because of reference to auction house realised price but stunt later only to find out that the "bargain" only worths a friction of the purchase price at the time of resell? It's a crime in China for gov official unable to explaine the source of income (i.e. officers receiving large amount of money without a valid reason is a crime) but Discipllinary Committee of the Chinese Communist Party will regard auction income as a legitimite income thus both parties involved in auction, even with paper trail, will be trouble free.
I am not saying that all lots in Hosane auction are bribes or trying to bring down MCC collectors passion, i am just trying to offer an alternative view into understanding auction results and caution everyone to do the research before giving away their hard earned money.
