It is master die doubling. It is similar to a doubled die, but when a master die is doubled, all of the dies created from it will show the same doubling, so there will be millions of coins minted that are all doubled. When you have large numbers of coins that are all the same, they don't carry a premium over a normal coin.
In 1972, this happened at all three mints. Many of the P,D, and S mint cents will show this same doubling.
