There is no straightforward way to tell, just by looking at the coin. To determine a coin's value, you need to consider its denomination, date, mintmark (if any), and condition (wear, damage, cleaning, etc.). When you know these factors, then you can look it up in a price guide. Check out my FAQ page for pricing and grading links : http://www.workingmancoins.com/FAQ/index.htm

A miss-stamped penny may be very valuable, especially if it is in excellent condition. Such a coin can be worth hundreds of dollars, depending on condition, year, and the nature of the error. Not all such coins are valuable, and typically it takes a coin expert to determine if a particular coin is valuable or not.
Generally, coins are valuable because of the price of the metals they are made from, but if you mean in a collectible way: One thing that makes a penny valuable is the date. They older the coin usually the more valuable. Another thing is the mintmark. For example 1943 pennies with a "S" mintmark are more valuable than pennies with no mintmark. Another thing is the condition of the coin. The less ware it has the more it's worth.
