Die chips are not a premium for the coin. They are die events. Giving a name to these is usually done by people trying to sell off common coins as something special. After you get seasoned into coin collecting, the newness will wear off and then you will see them as I mentioned. So don't buy any of these. They will be found on the coins in circulation. When this die chip happens, during the rest of the dies life, that chip will always be there or even expand even larger. Look for the real collectables. So when you get settled it, you won't have a book full of just common coins that later you realized you set aside and they are worth less than the 2X2's you put them into.
