why no d/d 0

just had this washington quarter graded, looks like a d/d, but cant see with 5x loupe I used a scope, but I guess 62d has no d/d, wondering why

Your coin displays strike doubling, aka machine doubling, shelf doubling and so on. This occurs individually at the moment of striking and die withdrawal, so it's not a feature of the die. Strike doubling is pretty common, and it's not considered a collectable variety.

What DWLange said plus it can’t be a DD as the mint mark was hand punched.
