Die Chips in LIBERTY on Lincoln Cents became popular for some collectors in the 60's. In the handbook Howard O Hardy developed a schematic method for identifying and classifying Liberty Chips that was called the Hardy Index System. The index was applied to over 1800 illustrations by John Gedko for this handbook. The last illustration in the book was a 1970D. It seems that interest in the Guild and Die Chips in LIBERTY faded with the passing of Mr. Bush. For whatever reason there seems to be very few Die Breaks in Chips on Lincoln Cents minted in the 70"s and 80's. Then starting in the 90's we started seeing more.
Your die chip is a "DL+" indicates a break of ½ or more, but less than ¾ that extends below the lowest level of the letters.
