The best? That's sort of a difficult question to ask. There are dealers/sites that specialize in different coins/series. If you could narrow the scope down a little it would help. For example, if you are looking at Lincoln cents, it's hard to beat: http://www.thepennylady.com/ http://02a7097.netsolstores.com/offline.aspx (currently on hiatus) http://www.angeldees.com/ For Indian Head Cents I'd look first at: http://www.indiancent.com/ http://www.thepennylady.com/ Other sites I visit regularly: http://www.markfeldcoins.com/ http://www.jjteaparty.com/ http://www.frankcoins.com/ http://www.ldrcoins.com/ These are a few of my favorites there are dozens more, depending on what you're looking for. Others can add their favorite sites and you'll have a list of top quality people to do business with.
Wow Pennyguy that pretty much covers it. All great sellers/dealers with reputations of honesty and integrity
