Rush,
I don't have any of the really rare ones. But the extra-fines that I do have would go for $65 to $150. The very-fines go for $40 to $90. The VG/F's go for anywhere from $10 to $40 or so. Those in good condition could cost as low as $6. I do have a couple of semi-key coins. One is the 1901-o, which is in very good condition and would cost $65. The 1896-o is just in good condition, but it would cost $27. I doubt that I'll ever find a '96-s or an '01-s or a '13-s, which are the really scarce, key coins of the series. But, man how I would love to find one of them. LOL
