Got my answer from here, some guide. >> http://coins.about.com/library/coin_values/bl_wheat_cents.htm
"The wheat penny values in this price guide are the actual prices coin dealers will pay you for your wheat pennies. These are not the retail coin prices found in nearly all other coin price guides, which, if relied upon to appraise your wheat cents, will result in great disappointment when you go to sell them. If you use a wholesale coin value guide like this one, you will get an honest appraisal of what your wheat pennies are worth if you had to sell them today.
All wheat pennies are worth at least triple their face value unless they are badly damaged or almost totally worn out. Some wheatback cents, though, called key dates, are worth hundreds, even thousands of times their face value! Find out how much your wheat pennies are worth in this coin values table below.
