I've found a couple really great old-fashioned mail bid auctions. I get a monthly list from each. They also have their list on the web so you can enter your bids from there also. The 1st is American Coin and Stamp Brokerage, Inc. out of Merrick NY www.acsb.com and the 2nd is Lake Norman Coins & Auction Co. Before we lost the site, we had a thread going about "holed coins". These people have quite a few in their auctions. www.coinmall.com/duskie/ If these links don't work, you can always find them on www.coinsheetlinks.com
