Cowan's Auctions Special Collections

Cowan's Auctions, who I have been doing consulting work for, has started to do some online-only timed auctions.  This is different from online auctions like eBay, in that Cowan's has expert appraisers in a number of categories of auction items.  You can go to their site to bid, or to use their very extensive database of sold and pending items to estimate the value of your own goods.  They also have a presence on Live Auctioneers, where you can bid from an App on your Smartphone.  See also their well done Facebook page.
