When I look at better coin auctions, I stick with: -- eBay -- Great Collections -- Heritage -- Stack's & Bowers Why? Because they are the only ones I'm aware of. And I'm leaning strongly toward EAC material. What are others that I missed and should be looking at?
If you are a member of EAC they have auctions usually at their yearly get together. Some good stuff in these auctions. Check out their web site for info. I'm guessing they have one.
If you are leaning toward EAC material I would definitely recommend Goldberg auction. They frequently have nice copper material. I like the EAC auctions as well, you can find some rarer material there, but the coins will often be lower grades and sometimes with problems. This link will take you to their auction archives where you can look at their past auctions. http://images.goldbergauctions.com/php/auctions.php Look at 115, 112, possibly 104, 103, frankly most any of their Pre-Long Beach sales are good.
I frequent Kaufman Realty & Auctions in Sugarcreek, Ohio. Third Tuesday of each month is a coins only auction with 4-500 lots. Some months have an additional 1 or 2 coins only "special" auctions. They seem to have better stuff than many other coin auctions. Some highlights of this months auctions: plenty of CC Morgans, several 3 legged Buffalo nickels, gold coins - including an 1856-S $3 XF, 1909-SVDB XF, lots of nice Bust halves, 1795 half dime VF, 1793 Chain cent. I've seen coins sell there with up to a $30K Redbook value. Their white elephant lots can be awesome - one of my buddies bought a cardboard box full of proof sets (later found to have about $200 face) for only $100, and that was not the only time boxes of lower end collectable coins were purchased at below face value.
