This article is almost a year old, but I still found it interesting: http://www.livebusinesschat.com/smf/index.php?topic=4738.0 "The market is getting exciting. A few hours ago, a 1989 3.3 oz silver clear claw god of war & wealth NGC PF 69 UC sold for $6500 in the Hong Kong Champion auction after very aggressive bidding by in-person bidders. Online bidders were blown away - Not a single one was able to get a bid in (I tried, and failed). Prices started at $1000 and exploded within seconds to $4000, and then sprinted all the way to $6000 before there was any hint of hesitation by the bidders. They wanted that coin, and they wanted it bad. The whole time, the exact same coin had been sitting on LBC's Ebay list for a month, priced at only $1500. It was purchased from the list within minutes after the $6500 sale. " I like (and agree with this bit): "...Arbitragers will start buying coins from Ebay, and moving them to China. ..."
