1993 Washington quarter D over horizontal D?? 1 1

I’m not sure what to think on this one it’s looks like the quarter was spun 90 deg and struck again, you tell me.

Welcome Basinger68 .  It Looks normal to me . Other than the coin has been turned?

I see nothing out of the ordinary.

If it was struck again, it would show on the whole coin, not just the mint mark.  
It is just some sort of stain or mark, nothing significant.

Just some reference for you, the mint began phasing out the hand punching of mintmarks in the mid eighties.   By 1990 all hand punched mintmarks had been phased out, so it would be impossible for you to find a D over anything on a coin from 1993 unless a mint employee was doing some creative midnight manufacturing on his/her own.

If you compare it to a clean certified coin there is very little that is off except for the hit to the MM, stains, and scratches on the op's coin.

I see evidence of wear and circulation on the quarter you have. It took plenty of hits that displaced some of the metal on the mintmark as I see the depression across it from a relatively hard hit. As for the circular marks on the obverse, I have seen those marks on a lot of Lincoln cents, some nickels and Roosevelt dimes as well. Before I knew any better, I sent one for grading and it returned as details - physical damage.

I think that circular mark comes from a coin counting/separating machine like the self dump machine in a bank or a Coinstar machine. 

I also agree with @Coinbuf as the mintmarks were put onto the master dies so things like RPM disappeared from modern strikes. Anything involving a minor displacement of a mintmark from this time period usually involves a strike from a loose collar around the planchet causing the planchet to bounce during the strike, or a loose die in the press, but does not create a new variety.

Or possibly from a coin rolling machine of the type that crimps the roll on the end, leaving part of the coin exposed.
