I bought this 1926D penny and noticed the reverse is rotated about 10 degrees to the left. How far can a penny die be rotated and still be within spec's?
Actual US Mint tolerance is 27 degrees. They are not collectable unless there is a 45 degree rotation, minimum. That means when you flip over any US coin, the top of the reverse has to be pointing at either 1:30 or later, or if it's counterclockwise, the top has to be pointed at 10:30 or earlier. The 26-D cent is fairly common with this minor rotation as in the OP's photo. Doesn't carry any premium, however.....
