A die chip is just a part of the field that has broken off the die leaving a void. The newer single squeeze dies have a lot of die chips because the design is shallow. After the chip happens, all coins after that will have that die chip showing on them because of the void that the die has in it. It can continue to break down, or it may stop there. But they usually don't retire the die because of this small issue. It takes a lot of them to retire a die. The newer 2005 Buffalo nickels had a lot of die chips on them.
