Hi JMC, and welcome to CT. Between the 2010 Red Book - A Guide Book of United States Coins ( http://www.amazon.com/Guide-Book-Un...675/ref=sr_1_3?ie=UTF8&s=books&qid=1265986418 ) and closed ebay.com auctions, you can get a good idea of what your coins are worth. The Red Book is good because on some coinage, it has value for error coins/sets. -LTB
