1955 D Lincoln Wheat Cent

I agree with circulation flattening. 'Fat' letters and numbers are not always sure fire signs of doubling. Cool find none-the-less.

The devices flattening stop when they are the widest/tallest? Why? Because the devices are tapered, the tops (narrow part of the devices) get flattened outwards to the outside edge of the coin (the base of these tapered devices) Thus they narrow tops are flattened to the edges of the devices. (the base) Try some of the upper metal gets worn off of the devices. But the bases are usually the end of flattening:

Note the rims on these cents? Note that when the rim wore off of these cents, the devices were still pretty strong. Note when the rims are gone?

The devices go away a lot faster then. Thus most collectors prefer Fine or better coins better for filling albums. (Always up grading when a better example is found)

Thank for all the info yall! Much appreciated. My confusion is probably because I haven't found a double die myself. I will.
