Need Help With 1960-D LMC

The tilted MM is normal since it was added to the working dies by hand up until 1990. Why we search for RPM's, at times the die techs would try to straighten them out, hence rotations, movement up/down, left/right. The doubling is either MD, mechanical/machine doubling called Strike Doubling or as is here is called master die doubling where the master die hubbings that created this passed it down to multiple Working dies, thereby stamping the same doubling on many coins from different dies. You'll see this same doubling on other 60D's w/ different MM locations. Not considered a true collectable Doubled Die.
