value for old coins is best determined by having them graded, however that in itself costs. I would only send a coin in to have it graded if I knew it was a collectible date/mint mark, etc. and it would have to be in excellent condition, nearly uncirculated. All that depends of course on the rarity of the coin. Ed will probably chime in here and give some better info.
I suggest getting a current edition of the Red Book on US coins to get a better understanding of what is rare and that might be worth having graded.
