1960 Lincoln struck on a planchet that split before it was struck, which weighs in at 1.7 grams. Has a strong, full date yet is missing many details as a result of it not being thick enough to get the full strike of the dies. This is one of many errors that many collectors - esecially dealers - don't understand. In fact, I saw this in a junk bin and asked what he wanted for it. He looked at it and said "take it!" So, I did. ~Joe C.
