Dred Scott was never overturned by any subsequent decision of the supreme court. It was superseded by the 14th amendment.

Plessy, contrary to popular misconception, was not overturned by Brown vs Board of Education. If you read the opinion in Brown, you'll see that it went through contortions to try to explain why Plessy wasn't controlling in that instance. Subsequent to that, Plessy was largely if not entirely superseded by federal civil rights legislation.
