1970 1c Double Die Obverse?

Just some minor MD

Look at the areas you are looking at. If it is on the outside/inside of devices, that is where die wear/DDD/machine doubling affect the coins. Look at the centers of the devices to see spread on the devices:

Spread on the centers of the devices is what to look for. Not the outside/inside edges of the devices:

Spread lines on the centers of the devices:


Look for the spread in size of the devices on the centers.
Die wear is a die event.
Machine Doubling is a striking event.
A doubled die can have Machine Doubling. Because the die was doubled and the machine was loose. But a loose machine never creates a doubled die. The reason we call them "doubled dies"? Because the doubling is on the die.

Look at the centers of the devices. if no hub doubling is not there; move on to the next coin. Spending more time than that on a normal coin, will find you a non doubled die coin and distract your time away from the real search. Just move on if your eye doesn't see it the first time. When you find the real deal, your eye will spot it in an instant. Don't believe that yet? Wait till you find one, then you will know I'm right.
