Most experts will not answer general questions of "How Much Is This Coin Worth?" mainly due to the fact that there is no simple answer. Dates, mintmarks, denomination, condition of the coin, and other factors provide a wide range of value quotes. Just the date or type of coin is not enough information to answer such a question. The best advice is to obtain a book from a bookseller or local coin shop called "A GUIDE TO UNITED STATES COINS" by RS Yeoman - The "Red Book" as it is called. This book is the mainstay for coin values for dealers and collectors. The ISBNs are = ISBN-10: 079482267-3 ; and ISBN-13: 978-079482267-5. Bear in mind that the quotes in that book are top-end retail; most collectors or dealers will most likely offer slightly less. You might find older volumes in some libraries; but these may have outdated quotes.
