If there is any doubling, it is important to note that there is one doubled die that no one pays any attention too as it is practically considered as normal. It is the result of a master die being doubled. Without going into all the "who shot John" on it, probably half of all 1972 cents exhibit the minor doubling due to that master die situation. It is one example that points out that not every doubled die is valuable. Another master die situation effects Jefferson nickels and about half of all War Nickels are minor doubled dies with doubling on the obverse. Thanks, Bill
