Just watched this, thought it was interesting and wanted to share. GreatCollections is a company I have done a lot of business with, and I really like their site and online-only auction format. They are much smaller than say Heritage, but I have purchased more coins, and have had better customer service from Ian and his team. If you've never used GC before, as a buyer or seller, I recommend you check out this video and give them a shot. http://www.coinweek.com/people-in-t...o-founder-ian-russell-interviewed-larry-king/ At one point, Ian estimates there are upwards of 10 million coin collectors in the US.
For certified stuff like I used to sell at GC, I do as good or better on eBay even after the fees. Though I usually do best selling high end stuff to dealers. Just my experience. But good for Ian!
