Variety Vista shows no doubled dies for 1973 D and the rpm's for this date are pretty minor still a nice cent and a keeper. http://www.varietyvista.com/02b LC RPMs Vol 2/RPMs 1973D.htm
Are you referring to the Mint Mark being Doubled Die? If you are then it's not possible because the Mint Marks were hand punched into the Obverse Die back then.
