Looks like a normal coin from the image provide. What is doubled on it? http://imgs.inkfrog.com/pix/coop49/1983P-1DR-001.jpg
Depending on what caused the doubling you are seeing. Flat shelf like would be machine doubling. If it is rounded it could be hub doubling. So...
It is a small date "D". The common one. The small date plain is the harder one to find. It is a lamination though.
Flat shelf like/reducing the size of the devices = machine doubling.

What machine doubling is that the dies were normal and during the strike a little die movement damaged the devices on the coin. Happens a lot on...
What your are seeing is the metal striations caused from the sides of devices that moved during a strike. Not a variety.
