.... and the dates. Some are very rare. Most dealers sell G/VG common dates for about a dollar or 75 cents.
And he that hath lyberte ought to kepe hit wel / For nothyng is better than lyberte / For lyberte shold not be wel sold for alle the gold and syluer of all the world. -Caxton's edition of Aesop's Fables, 1484
I would go by the current buy prices from dealers in your area so you can build a price off that. Avg. Date and Condition coins around here buy at .50-.75 and sell for $1-1.50. But better dates and conditions will require a book or the bay from there.
If they are decent shape than I would try to get them for 75cents each. If they were all junked up and crappy I would probably pay 40 cents each, only because there are some really valuable dates that are out there.
